Hi everyone,
I have a 1989 Sahara with a 4.2 and a Weber 32/36. Every few miles, particularly in stop and go traffic, my YJ will starve for fuel and quit running. I coast to the side of the road, and I'll pull the line coming from the tank to the fuel pump and suck on air until I taste gas. Reconnect line and then it fires up and runs perfect as before.
I thought maybe I had introduced air into the system after replacing my fuel pump and dropping the tank to replace a rubber fuel return line, filler, and vent hose. Maybe the Jeep could be burping out that air? But it keeps doing it, four times actually over a maybe 20 mile drive. FYI it has the fuel filter plumbed with the return line (picture attached); I've heard not doing so can cause issues.
Maybe I need a new sending unit, or could it even be as simple as a gas cap? I really don't like firing the parts cannon when I can't diagnose. What do you think could be the problem?
