How much fuel pressure do I need to have with factory - 12psi of boost?

bassically just tell me the factory setting of fuel pressure please =]

 

36 psi iirc

 

k thanx.

 

i run ~42psi

 

At zero psi, the pressure should be 35.6 to 37.0 psi. For each psi of boost you add one psi to the 37psi figure. As in 37psi plus 12psi.

You get to zero psi by just removing the vacuum hose from the FPR and plugging the vacuum line momentarily. Or for that matter you could just turn the key to ON, engine off to achieve zero psi.

There's a free online FSM available that shows the fuel pressure.

Fuel pressure at idle with everything connected up should read 28psi ...give or take a bit. I see 31-32 psi at idle.
