The marine engine fuel return line returns surplus fuel from the injectors and pump to the tank. It is used on marine propulsion and auxiliary engines on workboats, supply vessels, tugs and barges.
The fuel system stores, filters, pressurises and meters fuel into each cylinder, and on gas engines it controls the gas supply and air-fuel ratio.
Why it matters
Worn fuel parts cause hard starting, smoke, power loss and high fuel use, and a leaking injector can damage pistons and liners.
Common signs it needs replacing
- Loss of power under load
- Black or white exhaust smoke
- Fuel leaks or air in the fuel system
- Higher fuel consumption
How to order the right part
- Share the engine make, model and serial number from the engine nameplate.
- Send a clear photo of the old part and any numbers cast or stamped on it.
- Tell us the application (for example generator set, compressor, pump or vessel) and running hours.
- Ask about available options, condition (new or reconditioned) and lead time.
