Hi sparkfly,
and how bad of an UGHHHH was it?
Solderable pinhole or brazeable multi-hole or cut out a patch & weld in new steel or go tank shopping?

[sparkfly88]

Well, the whole tank interior is rusty.....

I'll take a photo of the UGH when I get home

I would suspect this is just the start of your hole finding experience. MY best advice would be to clean the interior of the tank with the method of your choice, which will find more holes by the way. Then get the Caswell tank liner kit.

In order to keep me riding, I removed most of the paint on the bottom of the tank as I was sorting out the electrical issue I had, and used "seal-all" in multiple coats to seal the leaks in the bottom of the tank.


I was looking into using POR15 in the tank, and maybe the caswell sealer.

I do like the por15 has color options though, to hide all the damage the rust has done.

I don't know about the POR product, but the Caswell epoxy is easy and effective. Avoid the Creme stuff, the white rubbery crap, as I have yet to hear of someone happy with it and many griping about how tough it was to remove even though it didn't work in the tank.

FYI: Get a three or four feet of that folded over brass decorative chain to use to scuff out the tank's interior. It has an edge that will knock off the big chunks of rust, and a rough interior helps hold the epoxy. Use masking tape to seal the known pinholes and the epoxy will seal them up. To keep me from blabbing on, search for the numerous threads regarding tank sealers.

Wholly Tank

+1 on the cleaning and Caswell liner. Just did a tank quite recently. Tank had previously been lined - I suspect quite some time ago. It was not leaking fuel (yet). Old liner had started coming loose and rust was all in the tank along with all those liner pieces. It was quite the mess.

Followed the advice of several members on the forum who had done this previously and ended up with what now appears to be a new tank inside. All of the old liner and rust was removed all the way to brand new/clean metal. Then added the Caswell liner. It was a long process, but worth the effort.
