anyone know what psi i need to set it at on my fuel pressure regulator? my car is a 97 eclipse gst. i also have a 1st generation super afc..i dont know what i should adjust all the knobs. help? thanks!
You set the base fuel with the vacuum line off and plugged to 43.5 psi. Once you reattach the vacuum line the fuel pressure will drop about 7-8 psi, assuming you have normal engine vacuum at idle. The fuel pressure with the line attached should change 1:1 with intake manifold pressure. Dropping when there is vacuum in the manifold and rising as there is boost.
