Ok I posted this in the YJ forum but thought I would post it here too. 93 YJ 4.0L. Engine was rebuilt around 2 years ago. Everything is new. All sensors too. Did a fuel pressure check on it today it is running at 90 psi. The Haynes manual says inspect the fuel return line for kinks and blockage. Did that I even unhooked the line at the tank and blew it out. Got fuel and air. The return is the one that does not have the filter on it right? HELP!!!!!
93 YJ SOA 2" springs front, XJ springs rear w/main leaf added, High pinon 9 inch rear detroit locker front Dana 44 ARB 4.56 Gears, 36 inch Irok tires too much to list. www.mijc.org
