Indmar Marine Fuel Filter – EFI All Models | Part #556003 Protect your Electronic Fuel Injection (EFI) system with this genuine Indmar fuel filter, compatible across all Indmar EFI marine engine models. Clean fuel delivery is critical for EFI engines — even small amounts of dirt, rust, or debris in the fuel line can clog injectors, cause rough running, and lead to costly fuel system repairs.

A critical sealing component that sits between the intake manifold and cylinder head — maintaining the correct air/fuel mixture delivery into your engine. A failed intake gasket is one of the most common causes of vacuum leaks, rough running, and coolant loss on the 5.7L Vortec marine engine.
