Indmar Marine Fuel Pump Replacement Kit – Replaces 556184 | Part #495187
Restore reliable fuel delivery to your Indmar marine engine with this genuine Indmar fuel pump replacement kit — the correct current replacement for superseded part 556184. A failing fuel pump is one of the most disruptive breakdowns you can experience on the water — loss of fuel pressure means loss of power, and in a complete pump failure, a stranded boat. This kit provides everything needed for a complete, reliable fuel pump service.
Compatible with: Indmar marine engines previously fitted with fuel pump 556184 on Malibu, Moomba, Supra, and Tige boats. Contact us to verify fitment for your specific model year
Searching for part 556184?
Part 556184 has been superseded and is no longer available. Part #495187 is the correct current replacement kit. If you have been quoted or have previously ordered 556184 — order 495187 instead. Same application, current specification, full OEM fitment.
What does the fuel pump do?
The fuel pump maintains the correct fuel pressure and flow rate to your engine's fuel injection system at all times and under all operating conditions. On an EFI Indmar marine engine the fuel pump must:
- Maintain precise fuel rail pressure for correct injector operation
- Deliver sufficient fuel volume at high RPM and full throttle on the water
- Prime the fuel system rapidly on startup — especially after extended storage
- Operate reliably across the full range of Australian summer temperatures
- Withstand the vibration and movement of continuous on-water use
A degraded fuel pump that can no longer maintain correct pressure causes lean running conditions, power loss under load, and hard starting — symptoms that are easy to misdiagnose as injector or fuel filter problems.
What is included in the replacement kit?
This is a complete replacement kit — containing the components required for a full fuel pump service rather than just the pump unit alone. Contact us to confirm exact kit contents for your specific engine configuration before ordering.
Signs your fuel pump needs replacing:
- Engine losing power under hard acceleration or at high RPM
- Hard starting — especially after sitting over winter storage
- Engine running lean — hesitation, stumbling, or popping under load
- Fuel pressure reading below specification
- Engine cutting out under sustained full throttle
- Loud whining noise from the fuel tank area
- Engine starts but dies immediately after startup
How often should you replace it?
The fuel pump is not a standard annual service item but should be inspected if any of the above symptoms appear. Fuel pumps in marine applications have a harder life than automotive pumps — constant vibration, temperature extremes, and the effects of ethanol-blended fuels common at Australian fuel docks all accelerate pump wear. If your pump is showing age or symptoms — replace it before it fails completely on the water.
The danger of ethanol blended fuel:
Australian fuel docks increasingly supply E10 and higher ethanol blend fuels. Ethanol is particularly harsh on fuel system components — attacking rubber seals, degrading pump internals, and absorbing water into the fuel system. If your boat regularly uses ethanol blended fuel inspect your fuel pump and fuel system components more frequently than standard service intervals.
Pro tip: When replacing your fuel pump always replace your fuel filter and water separator at the same service. A new pump pushing fuel through a clogged or contaminated filter is working harder than it should from day one — shortening the life of your new pump unnecessarily. Start fresh with clean filters and give your new pump the best possible conditions for a long service life.
