Mackvette1 Posted May 29, 2021 Share Posted May 29, 2021 Recently installed new oversized injectors, fuel lines, Return check valve, fuel filters and ran the overhead. Truck runs amazing going down the road 33 lbs of boost and pulls like a dream but runs like its sucking air and running ruff at idle. Seems strange but I can get it to smoothen our when I unhook the fuel supply line for a bit but no fuel suction. Seems to be on the return side if I had to guess but everything is new. Any help would be great thanks Quote Link to comment Share on other sites More sharing options...
