The factory plastic filter housing under your truck warps and cracks under heat cycles, eventually leaking fuel or oil. After years of heat cycles, it warps, cracks, and starts weeping fuel or oil — usually at the worst possible moment. A machined aluminum or iron replacement bolts on in under an hour and ends the leak cycle permanently.

If your 3.6L or 6.6L Duramax is leaking from a cracked housing, you need a drop-in metal fix that actually seals. Find the best truck filter housing replacement for your engine and your budget here.
Our Picks at a Glance
How To Choose The Best Truck Filter Housing
Your truck’s filter housing — whether for fuel or oil — sits right in the engine’s heat zone. The factory plastic versions degrade over time, which is why so many owners end up searching for a metal replacement. Before you order, lock down three things: the exact engine, the OEM part number, and the material.
Match the OEM Part Number First
This is non-negotiable. A housing that fits a 2004 Duramax won’t bolt onto a 2013 model, and a 7.3L Power Stroke unit won’t fit a 6.7L. Look for listings that state the specific OEM numbers they replace — like 12642623 for Duramax fuel systems or 926-959 for the 3.6L oil cooler — and verify against your truck’s build before buying.
Material Decides Your Lifespan
You’re choosing between billet aluminum, cast iron, and the factory plastic you’re trying to escape. Aluminum resists corrosion and sheds heat well, while iron offers a rugged, oxidation-treated surface for diesel fuel systems. Both outlast plastic, but the machining quality of the threads and sealing surfaces is what actually stops leaks.

In‑Depth Reviews
1. YITHSWAY 926-959 Aluminum Engine Oil Cooler Filter Housing
Our pick — over 4.5★ from 250+ verified ratings; the strongest balance of quality and price.
The 3.6L fix that ships with every seal, sensor, and bolt you need.
For owners of the 3.6L V6 in a Wrangler, Grand Cherokee, Durango, or Ram ProMaster, this is the definitive fix for the notorious plastic oil cooler failure. It is a full swap-in kit: the aluminum cooler and housing, a filter, plus a pressure sensor, temperature sensor, 5 O-rings, 11 mounting bolts, and 12 gaskets — everything is pre-installed and ready from the start.
The defining win is the material. Reinforced solid aluminum replaces the plastic that warps under heat and starts weeping oil, and it brings excellent corrosion resistance as a bonus. Buyers report completing the repair in under two hours, and the fit is repeatedly praised on the 2019 Dodge Grand Caravan with zero leaks months later.
At 2 kg, it is a hefty, confidence-inspiring chunk of metal — nearly four times the weight of a bare Duramax fuel head. The honest caveat: a handful of owners hit a faulty oil pressure sensor, so keep your old sensor as a spare if you want zero risk on that front.
Why it wins
- Full aluminum construction that stops heat warping and oil leaks for good
- True complete kit — sensors, bolts, gaskets, and filter included
- Fast installs reported, with one owner finishing in under 2 hours
Watch out for
- Occasional oil pressure sensor failures reported
- Fit is platform-specific, so verify your 3.6L year first
Reach for this if: you drive a 2016-2018 3.6L Chrysler, Dodge, Jeep, or Ram and want a single-box solution that ends plastic cooler leaks.
Keep your old sensor: a few units arrive with a faulty oil pressure sensor, so holding onto the original is free insurance.
2. BARTOO Fuel Filter Housing Head
A lightweight 0.52 kg Duramax head that is a gamble on thread quality.
This is the entry-level path to replacing the fuel filter head on a 2004-2013 Chevy Silverado or GMC Sierra 2500/3500 HD with the 6.6L V8 Duramax. It is a direct replacement, built with an iron body and an oxidation surface treatment, plus an aluminum billet base finished with an electrophoresis process to resist corrosion.
The weight tells the story here — at just 0.52 kg it is dramatically lighter than the 2 kg oil cooler kit above, which reflects the bare-bones nature of the part. The good news is it covers a wide OEM part-number range: 12664429, 12645619, 12639448, and 904-517, so it suits several model years.
Before you buy, know the honest trade-off. Owners mention the filter threads do not go all the way to the base, leaving a visible 1/8 gap between the housing and a fully-tightened filter. One owner also found the push primer (the manual pump that builds fuel pressure) too stiff to spring back, so the system wouldn’t hold prime. This part is for you only if you are comfortable inspecting threads closely during install.
The value read: it is the cheapest route to a metal Duramax head, but the thread machining is the risk you carry — check filter seating before you commit.
Best if: you want a low-cost iron head and are ready to verify thread depth and primer action yourself during the swap.
Think twice if: you expect a perfect spin-on filter fit — the short threads are the most common complaint here.
3. MK-Morzon 12642623 Fuel Filter Housing Assembly
A one-box Duramax canister kit backed by a full year of support.
This assembly targets the 2004-2012 Silverado and Sierra 2500/3500 HD trucks, plus the 2007 Classic models, and gives you the complete canister setup in a single order. The package includes the 12642623 fuel filter head, one TP3018 fuel filter, and the 12639277 water-in-fuel sensor — everything you need to refresh the whole system at once.
You get a safety net here: the seller backs it with 12 months of product service and a low-maintenance return policy, which matters in a category where fitment errors are common. It is a canister-style aluminum unit, and the seller says it is 100% tested before leaving the factory.
The verdict from owners is genuinely split. Some call it an exact match that primes the fuel extremely quick, while others report leaks right after install, including one failure while driving. Given the mixed quality reports, this is a reasonable budget canister kit, but you should pressure-test every seal before trusting it on the road.
The balanced take: excellent value if you get a good unit, but the QC lottery means you must check all sealing surfaces during install.
Best if: you want a complete canister kit with a year of seller support behind it.
Reality check: quality verdicts are mixed, so inspect the O-rings and priming action carefully before you button it up.
4. iFJF 12642623 Fuel Filter Assembly
The Duramax swap with the tightest fuel filtration and a metal bleeder screw.
Built for the Duramax 6.6L in Chevy Silverado and GMC Sierra 2500HD 2005-2013 models, this iFJF assembly earns its premium spot with real filtration upgrades. The TP3018 filter uses multi-layer media with a 15-micron outer element and a 5-micron inner element, plus a water separation efficiency of 98% — genuinely cleaner fuel reaching the injectors.
The head is machined from billet aluminum and protected by an electrophoresis process against oxidation, so it cleans up easily. A standout detail is the aluminum air bleeder screw that replaces the plastic OEM version — a small upgrade that removes a common failure point and improves durability.
Installation is the most-praised aspect, with owners describing a drop-in fit and the truck starting on the first try after priming. That said, the fit carries caveats: some note the 8-sided water-in-fuel sensor differs from the OEM’s 12-sided design, and durability ratings are mixed, with a few units failing within months. Check your LB7 model alignment carefully before ordering.
What stands out
- 98% water separation and a 5-micron inner element protect injectors
- Billet aluminum head with a tougher metal bleeder screw
- Easy installs reported, often starting on the first prime
What to verify
- 8-sided sensor design differs from OEM’s 12-sided
- Mixed durability reports — some units fail within months
Choose this for: the best fuel filtration in the list — the tight 5-micron inner element is the clear edge.
Look elsewhere if: you want absolute certainty on long-term durability, since reliability reports are inconsistent.
5. LDCRE F81Z-9155-AC Fuel Filter Housing
A no-frills iron housing for the 7.3L Power Stroke, but the lid is the weak point.
This one is aimed squarely at the Ford F350 Super Duty 7.3L V8 from 1999 through 2003, replacing the Motorcraft FG1057 filter setup. It is built from iron with a strong structure meant for a long service life, and the machining targets the removal of iron oxide and solid impurities before they reach the fuel injection nozzles.
Installation is described as fairly straightforward — owners advise good lighting and a long, thin screwdriver to lift the passenger-side lines into place. The housing itself bolts in as a direct replacement without modification.
The recurring pain point is the lid. Several customers note it arriving so tight that it tears the plastic molded nut, and one described fuel pouring from the top within minutes. Given the low review count and these lid failures, this is a budget gamble best suited to someone who already has the tools and patience to wrestle a stubborn cap.
The honest warning: the iron body is solid, but the over-tightened lid is a real frustration that has ended several installs.
Best if: you have a 7.3L Power Stroke, want iron construction on a budget, and own a strap wrench for stubborn lids.
skip it if: you want a guaranteed straightforward install — the lid-tightness complaints are too frequent to ignore.
6. iFJF 10226035 Fuel Filter Assembly
The rescue part for 6.5L diesels when the original is long discontinued.
This assembly is a lifeline for owners of the 6.5L V8 diesel in Chevy and GMC trucks, vans, and SUVs from the 1990s — a platform where the original part is no longer available from the dealer. It replaces OEM numbers 10226035, 10154635, and 10183997, and it ships as a complete fuel filter kit ready to install.
The metal housing is the durability play here, standing up to far more abuse than the aging plastic units it replaces. Fit is the headline across owner feedback — exact-fit reports come from a 1992 Chevy Silverado 3500, a 1994 Detroit 6.5 TD, and a 1991 GMC 6.2 diesel, so the coverage across those years is genuinely proven.
The one consistent knock is the filter cap, which owners describe as insanely over-torqued from the factory — it doesn’t leak, but you will likely need a strap wrench to get it off at the first filter change. For a hard-to-find OEM replacement, that is a minor price to pay.
The pro move: if you own a 6.5L, this is the aftermarket part that keeps your truck running when OEM supply is gone — just plan for a strap wrench on the cap.
Best for: 6.5L diesel owners who need a true drop-in replacement for a discontinued original part.
Plan ahead: the factory-tight filter cap will demand extra force — a strap wrench is your friend at the first service.
7. CARMOCAR F6TZ-9B246-BA Fuel Filter Housing
A chunky 1.93 kg iron housing built for the first-generation 7.3L Power Stroke.
This housing fits the 1994 through 1997 Ford F-250, F-350, and E-350 with the 7.3L Power Stroke diesel, replacing part numbers F6TZ-9155-AB, FG1054, and AP63424. At 1.93 kg, it is the heaviest iron unit in this lineup, so that mass signals a sturdy build aimed at years of service.
It is designed to strip iron oxide and dust from the fuel before it reaches the injection nozzles, reducing mechanical wear and improving reliability. CARMOCAR backs it with a 1-year service period and promises a response within 24 hours if you hit a problem.
The owner experience is polarizing. Some report it arrived quickly and fit perfectly, while others describe fuel leaking from multiple ports on install and a plastic lid that broke off, with the replacement lid screwing on backwards relative to the OEM part. The raw weight suggests durability, but the machining consistency is clearly the risk you take here.
The measured view: heavy iron construction suggests longevity, but the recurring leak-at-the-fittings reports mean you should budget time to chase seals.
Best if: you have a 1994-97 Power Stroke and want the most substantial-feeling iron housing available.
Be prepared: multiple owners hit port leaks and a brittle lid, so keep a sealing kit handy for the install.
8. Dorman 904-558 HD Diesel Fuel Filter Housing
The name-brand metal housing that undercuts a dealer quote by hundreds.
When you want a brand you can trust instead of a gamble, Dorman’s 904-558 is the pick. It is a direct replacement for the original fuel filter housing on select Chevy and GMC Duramax models, made to original equipment specs and ready to install with the necessary hardware included. It carries a limited lifetime warranty, which is the strongest guarantee in this entire list.
The fit has been extensively tested, and owners confirm it — one swapped the metal Dorman unit in after a plastic version kept leaking, and the metal piece worked perfectly like factory original. Another owner on a 2002 Sierra 2500HD LB7 with EGR confirms correct fuel line angles and zero leaks.
The price makes the value case: one owner notes the Chevy dealer quoted for this repair, making the Dorman part a fraction of that cost. The main recurring caveat is the primer pump, which some owners find can introduce air leaks over time, and a couple report the seals leaking right from the start. Verify the 904-558 part number on your primer bulb before you install.
Why it earns trust
- Limited lifetime warranty — the best protection in this list
- Extensive fitment testing across Chevy and GMC Duramax models
- Owners call it a fraction of the dealer repair cost
What to check
- Primer pump can develop air leaks over months of use
- A few units arrive with weak seals, so inspect before install
Pick this if: you want a big-brand, lifetime-warranty part with proven fitment over an unbranded bargain.
The small catch: the primer pump hardware is the most common failure point, so monitor it after a few months.
9. HS Motorsports Billet Fuel Filter Housing
The American-machined billet upgrade that erases the 6.7L plastic bowl worry.
This is the premium answer for 2011-2016 Ford 6.7L Power Stroke owners in F250, F350, F450, and F550 trucks. HS Motorsports machines it from billet aluminum in the USA, replacing the problematic plastic fuel bowl that turns brittle with age and starts leaking. It retains the factory water-in-fuel sensor, so you keep that function intact.
Owner feedback is uniformly enthusiastic. One buyer describes a perfect fit on a 2015 F350, with a super smooth installation where you feel a positive stop when the housing seats — no second-guessing about whether it’s on right, and no worry about cracking a plastic part. Another calls it a great upgrade over the factory plastic with zero issues so far.
Quality wins people over most here, and it shows in the details: the housing is a little shorter than the stock plastic unit but fits just fine, and the included fittings and O-rings are all accounted for. The only note is that you must keep your factory sensor and install it into the HS housing — it doesn’t come with one.
The premium verdict: if you own a 6.7L, this is the definitive cure for the brittle plastic bowl — a clean, confidence-inspiring swap you do once.
Buy this for: the confidence of billet aluminum and American manufacturing on a 2011-16 6.7L Power Stroke.
Remember one thing: you must keep your factory water-in-fuel sensor and move it into this housing — it is not included.
Understanding the Specs
Material: Aluminum vs. Iron vs. Plastic
Material choice—billet aluminum, cast iron, or plastic—is the single biggest durability decision. Billet aluminum resists corrosion and heat, which is why it is the premium choice for oil coolers and 6.7L fuel bowls. Iron offers a rugged, oxidation-treated surface for diesel fuel heads and carries real heft. Factory plastic warps and cracks under heat, which is why you’re shopping for a metal replacement.
OEM Part Number Match
Every housing replaces a specific factory number — like 12642623 for Duramax fuel systems, 926-959 for the 3.6L oil cooler, or F6TZ-9B246-BA for the 7.3L Power Stroke. Matching your truck’s exact engine and model year to that number is the difference between a 30-minute bolton and a frustrating parts run. Always verify before you click buy.
