1988 F-350 with 7.3. I bought it not running. Determined the IP needed replaced. Bought new IP and installed it and truck fired right up and ran great. Drove it for a few weeks and decided I would replace the return lines. Got them all installed and I took it for a drive. Cruising down the road just fine until I let off the throttle and the truck died. Fired back up but only with foot on the gas pedal. After this happened I’ve had very poor throttle response and the truck dies every time I let off the throttle.
I have 5.5-6psi at the Schrader valve, new fuel filter, and new lift pump. I’ve checked the IP inlet filter screen and it is clean. I’ve tried the ATF in the fuel filter trick and it didn’t help.
Any help is greatly appreciated!
