Fitment Check

Match engine make, model, serial range, fuel type, hose rating, filter thread, flow direction, pressure, and mounting style before ordering.

Ask Parts Desk

Fitment

Start With Engine, Fuel Type, and Part Number

Fuel and air parts can vary by engine family, serial range, pressure, fitting size, flow direction, fuel type, and emissions setup. Use the existing part number or engine data plate whenever possible.

Safety

Fuel Leaks Are Not Guesswork

Replace cracked hoses, leaking fittings, loose clamps, contaminated filters, damaged flame arrestors, and suspect fuel pumps promptly. Use parts rated for marine fuel service.

After any fuel-system work, inspect for leaks, fumes, chafe, clamp security, and proper ventilation before starting the engine.

PMP

Fuel Delivery

Pumps, hoses, fittings, tanks, caps, vents, regulators, and connectors move fuel safely from tank to engine.

FIL

Filtration

Fuel filters and water separators protect pumps, injectors, carburetors, and engines from water and debris.

AIR

Air Intake

Air filters, flame arrestors, breathers, silencers, intake gaskets, and manifolds help the engine breathe properly.

Service

Fuel System Maintenance Prevents Hard Starts

Contaminated fuel, restricted filters, aging hoses, weak pumps, clogged vents, and dirty flame arrestors can cause hard starting, stalling, poor acceleration, and unsafe fuel leaks.

Change filtersReplace filters and water-separator elements on schedule or after contamination.
Inspect hosesLook for cracking, swelling, stiffness, chafe, loose clamps, and outdated fuel line ratings.
Check airflowClean or replace air filters and inspect flame arrestors for damage or oil contamination.
Verify fittingsConfirm threads, seals, clamps, connectors, and routing are correct and leak-free.

FAQ

Fuel & Air System Questions

How often should marine fuel filters be replaced?

Follow the engine manual, but many boaters replace fuel filters at least annually or when contamination, water, hard starting, or performance problems appear.

What does a fuel/water separator do?

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

Can I use automotive fuel hose on a boat?

No. Use marine-rated fuel hose that meets the correct fuel, permeation, fire, and installation requirements for the application.

What is a flame arrestor?

A flame arrestor is an intake safety device on gasoline inboard engines that helps prevent flame from escaping the intake in a backfire event while allowing airflow.
