Hole in the tank or filler neck, also check all lines coming from the tank for leaks.

And do you have a regular cherokee(xJ) or grand cherokee(wj)?? Your post and profile say 2 different things

the fuel pump may have been changed and the rubber seal did not seat properly or is not even there

Its a grand cherokee. and i took it in to get it fixed it was a number of things. like some high pressure line was spliced and the mechanic was shocked that it wasnt just spewing gas. thanks for the answers.

When I bought mine I got the same thing after I filled up past 3/4. I dropped the tank and found the locking ring that holds down the fuel pump to be loose. Since I already bought a new locking ring and seal I just cleaned all the dirt out (and there will be dirt and rocks piled up in there.) and installed the new stuff after inspecting the pump and filter sock. Havent had a problem since then. Parts cost me around $25 so it wasnt too bad, but it is labor intensive especially if you have the factory hitch which forces you to take the bumper cover off to get to those last two bolts. Oh and if you replace the seal make sure to lube it up real good along with the nut threads with a soapy water solution so you dont tear the seal.
