Fernando87mj Posted April 27, 2016 Share Posted April 27, 2016 My fuel tank leaks after filling more than 3/4 , gasket has been replaced twice and it still leaks and it's getting annoying. I have a new mopar seal this time waiting to be installed What tips/advice do you Guys have for replacing the seal . Here's how the lock ring is sitting as of now , it looks a little odd to me but i can't tell what's wrong Sent from my iPhone using Tapatalk Swb,4.0,d44,BA-10/5 Link to comment Share on other sites More sharing options...

ComancheKid45 Posted April 27, 2016 Share Posted April 27, 2016 Looks like the ring isn't locked in on the right side. Link to comment Share on other sites More sharing options...
benjy_26 Posted April 27, 2016 Share Posted April 27, 2016 Looks like the ring isn't locked in on the right side. That too. I didn't notice that on first glance. Link to comment Share on other sites More sharing options...
big66440 Posted April 27, 2016 Share Posted April 27, 2016 Looks like the ring isn't locked in on the right side. X2, get a brass punch and turn the lock ring clockwise, I would suggest lubing it with a little grease so you won't damage the seal Link to comment Share on other sites More sharing options...
HOrnbrod Posted April 27, 2016 Share Posted April 27, 2016 To me it looks like the top plate of the sending unit is not centered under the lock ring, thus the right side won't lock down. Link to comment Share on other sites More sharing options...
Fernando87mj Posted April 27, 2016 Author Share Posted April 27, 2016 Hmm oh okay I see it , I'll give that a try thanks a lot for the help guys ! Link to comment Share on other sites More sharing options...
ScottJeep Posted April 30, 2016 Share Posted April 30, 2016 And yeah, it is a TOTAL PITA to deal with that thing under the truck. The three times I've messed with the tanks/pumps/sending units I've ended up dropping the tank instead of the continued fight. For me I think I saved time and did a better job in the end. Good Luck!

Gene Posted May 1, 2016 Share Posted May 1, 2016 And yeah, it is a TOTAL PITA to deal with that thing under the truck. Hi Scott, Thanks for the comment. About 10 years ago I changed the gas tank, no problem dealing with the lock ring with the tank out. Last year I changed the fuel pump...Didn't remove the tank....I don't think I got the the lock ring very tight...so I have not filled the tank over 3/4 full. Much much easier with the tank out of the vehicle. But I had a full tank of gas when I changed the fuel pump... Thanks Gene Link to comment Share on other sites More sharing options...
mikekaz1 Posted May 1, 2016 Share Posted May 1, 2016 You can't over tighten the lock ring. They have 3 little tabs that press against the 3 hold downs on the tank itself. Tap it with a hammer till these touch and 99% of the time you will be perfect. If these aren't touching them (or really close) its not on all the way. It may still work, but its not right.

cruiser54 Posted May 1, 2016 Share Posted May 1, 2016 I recently made a tool for this purpose. Haven't used it in a real life situation yet, but mailed it to a buddy on another forum to try out. It's made of another old Jeep part. Guess the part. Link to comment Share on other sites More sharing options...
