my cherokee seems to leak gas out of the gas tank right where the sending unit is located, looks like it could be coming from the seam between the tank and sending unit. I was wondering if there is a seal, gasket, or o-ring thats there that may need replacing? any ieas would be appricited

haha. got a stereo? get under there with a large, flat head screwdriver and a mallet and tap that a plastic screw cap back on there a little tighter. the FIRST time a had to do this it turned quite a bit. but before i did there was a bad gas smell, and it even spilled a little when i filled up... idk if the stereo has anything to do with it, but i have one, so...

There is an o-ring that seals the sending unit to the tank. When you replace the seal it is advisable to replace the lock ring at the same time.
Yes, it is possible to replace with the tank still on the Jeep.

ummmm not sure what ur talkin about a stereo for? but i prolly should have put on there its a 95 and has a metal tank

any good place to get the o-ring and lock ring? i went to parts stores askin if there was a seal there and all they had to sell me was the whole sending units, so im hoping i can find just the o-ring and lock ring seperate

right, subs, i have often wondered if my subs aided in the looseness of the cap, thats why i ask. as far as having to replace the whole thing, i think that true, but only if you are having trouble with the pump itself. i think this is a seal issue, and you can deff. buy an o ring individually.

they do exist!

advance auto has the lockring and i believe its a flat rubber gasket that comes with it. i got one,just havnt put it on yet. and if your using a screwdriver, put some tape on the end,so you dont create any sparks.
