Fuel pressure

Fuel pressure

I have the 70mm tb, 70mm mass air, b-303 cam, 30lb injectors, alum heads,
1.7 rockers, 195lph fuel pump, much more to list. What is a good base
setting for the fuel pressure for my set up?

what car?
5.0 ? any other mods?

Stock fp should be about 42 to 45 at idle

stock fuel pressure regulator is fine.
Adjustable are bitchy to adjust, and you never want it lean.

Re: Fuel pressure

Ya I guess that would help. 91 Mustang GT. 5.0l. The other mod that probably
would factor would be an adjustable fuel pressure regulator, all the other
mods are not pertinent to the fuel system.
