My truck has an in tank fuel pump and I want to bypass it and put an inline fuel pump. It was starting rough and I had a diagnostic done. "They" said it was the fuel regulator. I replaced the fuel regulator and it is still still turns over rough after 15 secs. Now they are saying its my fuel pump but its pretty expensive to change out so I want to put an inline fuel pump in.
You would need to drop the tank pull the old pump out and put in a tube to get it to the pickup screen,,instead of the nightmare of putting in a inline pump,,, just put the one in the tank that's factory,,,you can either drop tank or take off the bed of the truck and slide it back
SOURCE: fuel pump fuse
replace fuel pump /fuel filter/screen/keep enough gas in tank at least 1/2 tank of gas at all times and change gas filter at 10,000 miles
SOURCE: fuel pump or fuel pump relay on 1989 Chevy Suburban 1500 4x4
Check in relay box on passenger side near firewall for fuel pump relay.
By -pass, no such luck that I' aware of, sorry.
