82baggeddatsun720 Posted September 8, 2017 Report Share Posted September 8, 2017 So am trying to build a Frankenstein z22e and i was wondering how much fuel pressure i would need for keeping it constantly running? Quote Link to comment
datzenmike Posted September 9, 2017 Report Share Posted September 9, 2017 Around 30 psi at idle but it will jump to 37psi when throttle is opened initially. The pump supplies anywhere from 43 to 65 psi. This is what the regulator 'sees'. The regulator is set for 36.5 psi. This is what the injectors 'see'. 1 Quote Link to comment
