Fuel Pressure - 6G Celicas Forums

Topic #50795 4 posts Started by Gmoney1
hey guys i know that noone really answers to my question on this forum but i jus wanted to know, what was the normal fuel pressure at idle ? Because my fuel pressure regulator is saying 60 psi. which i kno is way to much .
Could anyone help me out ? Thanx guys
43psi base with a raising rate of 1:1.
1 psi boost raises the fuel pressure by 1psi.
so if you boosting 10psi your fuel pressure should be 53psi.

ok so i am boosting to 10 psi , right . so at idle the Feul pressure is suppose to be 43psi.
yes, but not at idle. your FP should be set with the car NOT running. you have to bridge FP and B+ to turn the fuel pump on, and then adjust it to a BASE pressure of 43. once you start the car, the vac of the motor will change the reading at idle.
