After swapping out my tanks last weekend I finally got a chance to fill up my XJ today and just my luck the O-ring on the tank and pump is bad. poured gas at the gas station and on the way home. I've tried RTV and still leaks, less but still leaking. I looked around but can't seem to find just the gasket for the XJ metal tanks. Any one got an idea where I can find one or a way to seal it up?

 

napa auto part sell o ring don know how big when i did my pump took me three tries to get mine to stop dripping

 

there a pita to get in right might wanna take it out and just try it again one more time otherwise you might have to find a good one at ur local junkyard (atleast there pocket size)cause other than that i think you have to buy the whole sending unit hopefully not though

 

Hi...I recently changed my pump....the first time...the o-ring did not sit right....i adjusted its sitting and all went well....
I did not fill up my tank...how I discovered that the o-ring is not sitting right....move forward n reverse and do hard braking....if there is a leak...u can smell and see the wet area....

I did buy a spare o-ring....found it in ebay....

If there is no tear on ur o-ring....they might not sit right....

 

well i got one coming from the guys at morris 4x4 along with a new locking ring

 

buy a lock ring kit from advance auto. only place that sells the o-ring, and it only comes with the new lock ring.

 

Never done it on the Jeep yet but I've done it on Camaros and S10 Blazers.

I always clean out the area where the 0-ring and lock ring go back real good. Then I smear some formagasket on the 0-ring and set it in place, then I sit the sending unit/etc. in place and put the lock ring in place and drive it to the point where it is good and tight.

Haven't had one leak yet but there's always a first time.

 

thanks for the info guys, I got a new o-ring and lock ring coming from Morris 4x4
