fuel lift pump pressure spec.

[mpaulson]

What is the range that the lift pump pressures are to be within? Does anyone have this info?

the cp3 is ok between minus five psi to +22 psi most lift pumps set at 8 psi i have never seen one less than 7 or more than 9

i just added GDP 2m fuel filter and the guage between it and the cp3 reads 9 at idle.
(i had to make a bracket to fit it in with my bypass on the drivers side but all is well)
