Lift pump pressure

Viesti Kirjoittaja Forced_Induction »

What is the best lift pump fuel pressure for an M-Pump?
Mine runs 12psi with the relief opening at 35psi using the primer pump.
If I were to use an electric fuel pump, is 35psi too much pressure for the pump to be fed constantly?

Got a pump. Still no advice?

15psi is enough if you can keep it up all the time. There won't be any problem with stock elements but if you are using 8mm elements, electric fuel pump is needed. 35 psi isn't too much but it doesn't make any difference.
