Hello,
I did a search on the keywords in the title of this post. Planning to replace a leaky oring with a new OEM o-ring.
Some background: I had trouble getting a new fuel pump assembly to fit when I replaced it, even though it was suppose to be OEM for our '89 Cherokee. Had to snip off some of the excess plastic material that serves as a stop for the fuel sender float arm in order to get it through the fuel tank hole. Then, when I put the fuel tank o-ring between the lock ring and the new fuel pump assembly flange it didn't seem to fit quite right. I took a chance and used that o-ring anyway. Now, after filling the tank, it leaks from around the lock ring a very small amount -- but noticeable with gas smell and very small spot on the driveway..
So, I've ordered a new OEM o-ring and hope it will fit better than the one that came with the pump/sender assembly.
My first question: is it possible to install the new o-ring without removing the fuel pump/sender assembly from the tank?
Two of the posts I found on the subject:
http://www.naxja.org/forum/showthread.php?t=54156&highlight=replacing+fuel+tank+o-ring
and
http://www.naxja.org/forum/showthread.php?t=31355&highlight=replacing+fuel+tank+o-ring
In the former post long-time Member Matthew_Currie says "... If all you're replacing is the O-ring, you can probably get the old one off and the new one in without actually removing the sender. ..."
Has anyone tried this? Can you get the o-ring over the lock ring without ruining the o-ring? I'm thinking this would eliminate the difficulty of trying to fit the unit back into the small hole in the bottom of the tank. Downside, of course, is that I'd have to disconnect and pinch off outlet and return fuel hoses and disconnect electrical connection.
In the latter post sage Forum Addict old_man says "... I guess I'm going to get some sealer that will hold up to gas and goop it before I put it back together. I may get a new circular retainer from the dealer and see if it helps any...."
Has anyone actually tried using a sealer in addition to (or instead of) the OEM o-ring with success? What sealer works? Silicone? Old_man, did you ever try this approach?
And has anyone replaced the retainer and found that that replacement alone stopped the fuel tank from leaking?
