Sloshing the rivets in solvent, and drying prior to setting in the tank was in the manual I got from Vans, and it's dated 2011.

Default Excellent method for penetration . .

The fuel line will bulge out and you can squeeze pro seal in. Carefully wipe clean and do the next one. Simple and no tank removal needed. I was lucky to do mine to an unpainted fuel tank.
No further leaks
You can pick your sealant, but this is the best (technically) method to ensure the sealant penetrates any gap around a rivet, the pressure is at least 200X what can be developed with any in-tank vacuum.

Timely thread, good info, as the drain flange on my left tank is leaking. I hoped I had taken care of it by using the syringe method on the exterior, and recoating the shop heads on the interior, since a build error left gave me an extra fuel cap on the inboard edge of the tank to give me access. But, it failed the leak test this morning. So I guess a full R&R of the flange is next. I am not sure there is room and geometry to get a bucking bar in through the extra fuel cap. Does anyone know of a countersunk closed-end blind rivet to replace the AN426AD3-4's used for the flange?

This is good information. I too have several rivets weeping on the underside of the left tank. I?m considering this procedure but I?m a little hesitant as I?m not the builder and have never used pro seal.

Do you have a picture of the syringe and fuel line applicator? Do I need to mix the pro seal, or does it come in a package ready to use?How long after squeezing the plunger do you wait to wipe the excess around the rivet? Does the tank need to be empty? How long should you wait before filling the tank? Can you use this method on a painted aircraft? If so, what are things to watch for and to be aware of?

I appreciate any information.
Thanks,
Pat Moran

I had a 601P Aerostar years ago. Those that have owned one well know of the propensity to get fuel leaks. I was told to use a Click Patch to solve the problem. Used to carry some on board with me. was told that is what the airlines use. Used them more than once and they worked.
