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.
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.

Related Fuel Supply Module Service Parts
The low-pressure pump works together with the high-pressure pump inside the Mercury Fuel Supply Module. When diagnosing an FSM fuel problem, test both sides of the system and inspect the internal seals before replacing parts.
Mercury 8M0245916 High-Pressure Fuel Pump
The matching high-pressure fuel pump used in compatible Mercury Fuel Supply Module applications. It provides the fuel pressure required by the engine's electronic fuel-injection system.
What This Part is Used For
The 8M0245917 low-pressure fuel pump supplies fuel into and through the Fuel Supply Module. Its job is to maintain an adequate supply of fuel for the high-pressure side of the EFI system.
The associated 8M0245916 high-pressure pump then produces the higher fuel pressure required by the engine's fuel-injection system. Both pumps must function correctly for the engine to maintain consistent fuel delivery.
Low-Pressure vs. High-Pressure FSM Pump
| Pump | Function |
|---|---|
| 8M0245917 Low-Pressure Pump | Supplies fuel into and through the Fuel Supply Module so the high-pressure pump has an adequate fuel supply. |
| 8M0245916 High-Pressure Pump | Produces the high fuel pressure required by the engine's EFI system. |
Common Signs of Low-Pressure Fuel Pump Problems
- Hard starting or extended cranking
- Fuel Supply Module is not receiving adequate fuel
- Loss of power during acceleration
- Engine hesitation under load
- Engine may run normally at lower RPM but lose power at higher RPM
- Insufficient fuel supply feeding the high-pressure pump
- Low-pressure pump fails electrical or fuel-delivery testing
Why Test Both FSM Pumps?
Problems on the low-pressure side can create symptoms that appear to be a failing high-pressure pump. If the 8M0245917 low-pressure pump cannot keep the Fuel Supply Module supplied, the 8M0245916 high-pressure pump may not be able to maintain proper fuel pressure.
For this reason, fuel delivery and fuel pressure should be tested before replacing either pump. If the FSM must be opened, inspect the other pump, electrical connections, internal passages, and module seals while it is disassembled.

What This Part is Used For
The valve spring provides the closing force for the intake or exhaust valve after the camshaft opens the valve.
Proper valve spring pressure helps the valve follow the camshaft profile, return to the closed position and remain seated when combustion pressure is present.
Weak, damaged or incorrectly installed valve springs can contribute to poor valve control, loss of compression or abnormal valve-train operation.
When to Inspect or Replace Valve Springs
- During a complete cylinder-head rebuild
- After valve or piston contact
- When replacing damaged intake or exhaust valves
- If a spring is visibly damaged, corroded or distorted
- If spring free length or pressure is outside service specifications
- During a major powerhead overhaul
Inspect These Parts During Cylinder Head Service
- Intake valves
- Exhaust valves
- Valve stem seals
- Valve guides
- Valve seats
- Valve springs
- Spring retainers
- Valve keepers
- Camshaft lobes and journals
- Cylinder-head sealing surface
