This is a long shot I know, but I put my MJ on the road today low and behold 20 minutes in, the elbows on the sending unit flaked off some rust and started to weep. Better safe than sorry I ordered a gas tank and am looking for a SWB tank sending unit. Doesn't have to have a Fuel Pump, as I ordered a new one already. I'm located at 01033. My MJ is a 1989 SWB 4.0l auto 2wd (for now)
