When replacing the pump, it is necessary to use a new gasket (mounted between the pump and the engine block) to prevent oil leaks. It is also worth replacing the fuel filter and checking fuel lines for tightness.
A leaking feed pump can allow fuel into the engine oil (oil dilution) or cause external leaks (fire risk). Fuel supply issues can lead to engine stalling in dangerous situations.
Pump 4983584 draws fuel from the tank and supplies it under low pressure to the injection pump.
