i had the b&m adjustable fpr and yesterday when i started the car it barely idled and when i started driving it it would bog and backfire so i checked the fuel pressure and it was at 70. so i thought the fpr took a crap so i put back on a stock one today and the pressure was at 40 so i thought that was the problem but after i drive it for about 10 minutes it starts bogging and backfire then it kicks in and goes like normal. so when i got it home i checked the pressure and sometimes it would say 50 sometimes 65. i have an inline between my filter and rail but i turned the pump off to check the pressure. anyone know what it could be? thanks

 

First problem is you are turning off your inline pump to check pressure. So you are not going to have an accurate reading of the end result of intank and inline pressure. Just tap in after the inline and tune from there.
