All of these numbers are the same part.
Hard starting
A weak lift pump starves the injection pump. Long cranking after standing is a common sign.
Loss of power under load
If the engine pulls well when light but dies off under load, check fuel delivery and the lift pump.
Leaks
Fuel weeping from the pump body or seals means it is time to replace it.
Bleeding the system
Prime and bleed the fuel system after fitting the new pump.
