What should the fuel pressure be on a 93 F250 351w?
I have read 45psi. I have 40psi is that enough?

Truck falls on its face at 1900rpm, in park will rev higher than I care to push it.

 

Should be 35-38psi at idle with vacuum on the regulator and it should jump to 40-45psi when vacuum is removed from the regulator.

 

30psi @ idle, 40 psi when vac is removed. and 40 psi when driving just before the truck stalls.

Conanski I love when your reading one of my threads you are always help full.

if you remember back this is the same tuck I've done the swap in still having troubles getting it done.
