 Posted: Mon Sep 08, 2025 10:47 am Post subject: Leaking Fuel Tank Rivets |
 |
|
Guys:
I had a Leaking Fuel Tank Rivet about 10 years ago. With the fuel
level below the leak, I put a drop of Super Glue Liquid over the rivet.
No more leaking and I sort of forgot about since.
My other tank developed two leaking rivets recently. Discussions
on the Forum recommended Loctite 290. With the discussion on the Forum,
I thought Loctite might be better. I tried the Loctite and even forced
a little of it around the rivet by putting a little air pressure over
the rivet with a syringe as discussed. I let the Loctite cure for 48
hours plus. Added some gas and lowered the opposite wing to submerge
the rivets. The rivets still leaked and there was no Loctite
discoloration about the rivets.
I then lowered the fuel level again and cleaned the rivets with a
quick short spray of Carburetor Cleaner, wipe with a paper towel and a
blow dry with compressed air. I put a drop of Duro Super Glue
(ethyl2-cyanocrylate) over the head of the rivets and let it cure for 48
+ hours. I submerged the rivets again with gas. No more leaks and the
Super Glue is visible over the head of each rivet.
My conclusion is that Super Glue will seal rivet leaks on the gas
tank. Super Glue is not degraded or dissolved by gasoline (check the
internet). Has any one had good luck with any other simple sealant like
epoxy, J B Weld, silicone etc. Doc N123CV # 41087 and N784DC # 41862

I have been using B Weld. Drain fuel below the leaking rivet, clean
the rivet and surrounding area. Then a small dab of JB Weld.
Overnight cure and no leak. I have done this to three rivets so far.
I sand the JB Weld to a low profile and dabb white paint to hide the
fix. 2000 hours on airframe now since 2009. Really happy with this
airplane.

I've been fighting leaking rivets since day one. Did you apply the glue to the inside of the tank or just the outside??????

I used the the loctite that migrates, I think it is green. I pulled a very slight vacuum on the tank (very carefully with vacuum cleaner). I think I did it 2 or 3 times (let it sit for a day each time between. No leaks.

Bruce: We all have been applying the Doro Super Glue or JB Weld as Jim
uses, to the OUT side of the tank. The Super Glue dries clear and is
not noticeable on the paint. You can feel a slight mound over the rivet
(unless you put a real glob on the rivet). But the paint color shows
through. Put just enough to cover the rivet head-one small drop. I
would make sure the area it clean and no lose paint or debris around the
rivet. You might want to clean it a little with a dental pick. Good
luck. Doc

Thanks Doc, mine are on the underside of the tank/wing and I have tried the locktite without success. Super glue here I come. These were quick build wings by the way.
