After setting pump to auto fill gas flows out when pump shuts off. First fill kept shutting off so I placed as far as I could I think. Someone told me not to insert all the way. Three fills three spills
That was my next try. I am going to hold pump and manually fill letting off at intervals. I hope I don't need to look fuel gage in future to tell when full.
It's a function of fill speed. There's a way to fix it, but in the meantime, fill the last few gallons slowly. You'll hear it reach the top, but if you fill it slowly enough it will shut off automatically.
Takes a lot of patience or a really good feel for how many gallons you need.
05 and 06 had this issue - there is a 'stopper' in the tank neck that doesn't work...it's expensive...it just takes longer to fill up...my sister's 05 Liberty has the SAME issue...
Then why does my '99 TJ do it? Some pumps...not all keep kicking the nozzle off. Usually all the way in makes it worse so I end up hanging it halfway out and nursing it on the slowest setting.
The poppet valve inside the fuel tank at the base of the filler inlet sticks open (and sometimes sticks closed). Inserting the GM fuel hose flapper valve into the Jeep OEM hose is a decent, inexpensive and easy solution to permanently fix the issue. Sometimes, after a while, the poppet valve will close and stick in the closed position. Then you have to take a long screw driver and push it back open again. When this happens, the Jeep won't accept fuel, except at a super slow pace. Either way, it's totally worth doing the easy fix described in the linked threads above.
