well today i did a fuel pressure test and i read from 91-100lbs. of pressure at around 750 rpm's and reving it up it would go down to around 78lbs. And this is with a 2001 stock fuel pump and with the 60lbs. injectors. Well check this out i used to have my stock fuel pump wich was a flex fuel oringinal from my 2006 chevy, and so i just found out yesterday reading ''ZZebes THREAD - https://www.performancetrucks.net/fo...&postcount=347 , im not running a fuel pressure regulator cause I dont my stock fuel pump and wich the FPR was in my fuel pump assembly unit, also with my fuel return system. so what regulator should i run and do i need a return line now since i dont have one no more. what fuel system should i run imn my truck now, and thanks for all the help

what pressure should i set my regulator after i install one at idle and should it drop or it should nt drop after reving it up ????

 

I think your tuner will know what pressure to set it to. You will need a return line if you don't put the regulator back into the tank.
