Looking closely I could see a very small pin hole through the paint over the rivet. How do you seal a leaking rivet? What have I got to lose? I put a small amount of Supper Glue Jell over the pin hole and promptly pressed it down into the hole with a screw driver tip. Hardly noticeable and it stopped the staining with the tank full. What other fixes has anyone tried?

Doc N123CV @ N784DC Two 'easy first' things to try: Thinned proseal sealant in a syringe with the tip of the syringe cut off and a small O ring between the nose and the skin over the rivet. Use the syringe to force the proseal into any gaps around the rivet. Allow to cure. Another possibility is the technique developed (IIRC) for Mooneys. There's a certified wicking sealant that is supposed to wick into any gaps and cure. Rumor has it that the sealant is actually Loctite thread sealant. I honestly don't know whether it's supposed to be the 290 or the 08931; hopefully it's the former, due to price. It *should* wick into the gaps, but it would be possible to help it along with the same syringe trick mentioned above. In either case, the paint on/around the rivet should be removed, and it obviously shouldn't take much; don't force a teaspoon of stuff into the tank. ;-) Earlier versions of the proseal trick were done by pulling a slight vacuum on the tank with a blob of proseal over the rivet, but that has some hazards for the overall health of the tank. The syringe is localized to just the problem rivet, and doesn't affect the rest of the tank. Either of the above obviously should be done without any fuel contacting the problem area. Hope that's helpful, Charlie -- This email has been checked for viruses by Avast antivirus software. www.avast.com ________________________________ Message 3 _____________________________________ Time: 06:09:03 PM PST US From: Robert Jones Subject: Re: RV10-List: Leaking Fuel Tank Rivet You can drain the tank. Then have someone apply a vacuum hose to the filler port while you use a q-tip to put a little acetone on the leaking spot to clean it. Then use green Loctight on the leaky spot while applying vacuum. Pull the vacuum off while there is still green Loctight on the surface and just wipe it up. The vacuum should have carried it into the leaky spot where it will harden. I built my own tanks because quick build tanks often have problems with small leaks. Besides buttering up the ribs with proseal quite well, I stirred every every rivet in proseal before inserting it. I also encapsulated the shop ends in proseal before installing the aft baffle. They were built 7 years ago and there is no sign of any leaks.
