So I’m running a sweet tandem pump, 604 crate on alcohol. Regulator on back of log to return, fuel pressure sensor on back of regulator. My question is, at idle my fuel pressure fluctuates from 3 1/2 - 4 1/2 but doesn’t increase when I rev engine or anything. I have a slight hesitation on restarts but not sure if it’s fuel pressure related. Brand new quick car stepper gauges
