ive got a bosch pump which has been losing prime and leaking a bit of diesel. i cant see where this is coming from but i know it is the pump cos i can hear air escaping when i prime it. i'm going to be replacing the seals which can be got at without taking the pump off (havent got time to do them all at the min). however, i fitted an electric fuel pump to prime it for me in the meantime (wired up to glowplug relay). i'm going to be fitting a fuel pressure gauge and thinking of wiring up the electric fuel pump differently so that it is on all the time. my questions are as follows:
1)what should the internal pump pressure be? (wil 5psi be ok)
2)where are the usual places for an injection pump to be leaking from?
