Fuel Supply Module Service Parts
The high-pressure pump is only one part of the Fuel Supply Module. When diagnosing or rebuilding an FSM, inspect the low-pressure fuel pump as well as the internal seals. A weak low-pressure pump can restrict fuel supply to the high-pressure side, while disturbed or deteriorated seals can create leaks after the module is serviced.
Mercury 8M0245917 Low-Pressure Fuel Pump
The low-pressure fuel pump used with compatible Mercury Fuel Supply Module applications. This pump supplies fuel to the FSM so the high-pressure side has an adequate fuel supply.
Mercury Fuel Supply Module Seal Kit - 7333
Opening the Fuel Supply Module to replace a pump? Inspect the module seals and O-rings while it is apart. The 7333 FSM Seal Kit provides the service seals for compatible Mercury FSM applications.
What This Part is Used For
The Mercury Fuel Supply Module receives fuel from the boat's fuel system and supplies fuel to the engine at the pressures required for electronic fuel injection. Inside the FSM, the low-pressure and high-pressure pumps perform different jobs.
The 8M0245916 high-pressure fuel pump supplies the pressure required on the high-pressure side of the EFI system. If the pump becomes weak or fails, the engine may not maintain adequate fuel pressure under acceleration or load.
High-Pressure vs. Low-Pressure FSM Pump
| Pump | Function |
|---|---|
| 8M0245916 High-Pressure Pump | Produces the high fuel pressure required by the electronic fuel-injection system. |
| 8M0245917 Low-Pressure Pump | Supplies fuel through the Fuel Supply Module so the high-pressure pump has an adequate fuel supply. |
Common Signs of High-Pressure Fuel Pump Problems
- Hard starting or extended cranking
- Engine starts but cannot maintain proper fuel pressure
- Loss of power during acceleration
- Hesitation under heavy engine load
- Engine may run normally at low RPM but lose power at higher RPM
- Fuel-pressure testing indicates insufficient high-side pressure
- High-pressure pump fails electrical or pressure testing
Why Inspect the Entire FSM?
A high-pressure fuel problem does not automatically mean the high-pressure pump itself has failed. The low-pressure side must provide enough fuel to keep the FSM supplied. A weak 8M0245917 low-pressure pump can therefore cause symptoms that resemble high-pressure pump failure.
Test fuel pressure and fuel delivery before replacing components. If the FSM must be opened, inspect the low-pressure pump, electrical connections, internal fuel passages, and seals at the same time.
