Shop Fuel Filters Water Separators Diesel Fuel Filters
Fitment Check

Confirm engine brand, serial number, current filter part number, fuel type, micron rating, thread size, bowl style, flow direction, and housing compatibility before ordering.

Ask Parts Desk

Fuel filters protect injectors, carburetors, pumps, and engines from debris and water. Use marine-rated parts and inspect for leaks after service.

Find Fuel Filters Faster

Search by Brand, Part Number, Fuel Type, or Filter Style

Use the search box for exact part numbers, engine models, OEM references, spin-on filters, element kits, fuel/water separators, micron ratings, bowl styles, and related fuel-service parts.

Part Number First

Exact Filter Numbers and Micron Ratings Matter

The best match comes from the existing filter number, engine manual, filter housing number, or engine serial number. Similar filters may use different threads, seals, lengths, bowls, drain styles, fuel compatibility, or micron ratings.

Fuel System Care

Fuel Filters Often Pair With Hoses, Pumps, Fittings, and Tanks

Fuel contamination, restricted filters, failing primer parts, old hose, loose clamps, clogged vents, and weak pumps can cause hard starting, stalling, poor acceleration, and unsafe leaks.

Watch for Water

Water in fuel can damage pumps, injectors, carburetors, and engines. Drain or replace serviceable separators when contamination appears.

MIC

Match Micron Rating

Primary and secondary filtration may use different micron ratings. Follow the engine or filter-system recommendation.

SEA

Use Marine-Rated Parts

Fuel parts should be selected for the fuel type, marine environment, installation location, and safety requirements.

Service Help

Filter Only, Element Kit, or Complete Fuel-System Service?

If the housing is clean and compatible, a replacement filter or element may be enough. If you see water, debris, cracking, leaks, corrosion, damaged bowls, old hoses, or repeated restriction problems, inspect the full fuel path before the next trip.

Ask Parts DeskService KitsFuel Fittings
Replacing the filterUse the old filter number, housing number, engine serial number, fuel type, and micron rating to confirm the correct part.
Servicing diesel systemsCheck primary and secondary filters, separator bowls, water drains, O-rings, primer parts, and air bleeding requirements.
Servicing gasoline systemsUse marine-rated parts, confirm ignition-protected components where needed, and inspect carefully for leaks and fumes.
After installationPrime as required, check for leaks, verify clamps and fittings, and follow manufacturer start-up procedures.

Fuel Filters FAQ

Choosing Marine Fuel Filters

How do I find the correct marine fuel filter?

Start with the existing filter part number, engine serial number, filter housing number, fuel type, and micron rating. Photos of the filter and housing can also help.

What does a fuel/water separator do?

A fuel/water separator helps remove water and debris before fuel reaches the engine, reducing the risk of corrosion, poor running, injector damage, and carburetor problems.

How often should marine fuel filters be replaced?

Follow the engine manual and filter-system guidance. Many boat owners replace fuel filters at seasonal service or sooner when water, debris, restriction, or running problems appear.

Can the Parts Desk help match fuel filters?

Yes. Send the engine brand, serial number, filter part number, housing number, bowl style, photos, and whether the system is gasoline or diesel.

Shop Marine Fuel Filters by Brand, Engine, Filter Style, or Part Number
