Marine Fuel & Air Systems
Fuel Pumps, Filters, Lines, Fittings & Air Intake Parts
Shop marine fuel pumps, fuel filters, water separators, fuel hoses, tanks, fittings, carburetor parts, fuel injection components, flame arrestors, air filters, and intake hardware for reliable engine performance.
Match engine make, model, serial range, fuel type, hose rating, filter thread, flow direction, pressure, and mounting style before ordering.
Fuel systems are safety-critical. Confirm USCG/EPA hose ratings, ignition protection, leak-free fittings, ventilation, filter micron rating, and manufacturer service procedures before installation.

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.
Fuel Delivery
Pumps, hoses, fittings, tanks, caps, vents, regulators, and connectors move fuel safely from tank to engine.
Filtration
Fuel filters and water separators protect pumps, injectors, carburetors, and engines from water and debris.
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.
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.
