Interchange Gas Tanks

At this point I'm not too intersted in spending $100 plus for a tank. So I talked to a few folks and they suggested that I do the nuts and bolts in the tank to get rid of the rust. Some say that the pinholes in the tank can be saltered (did I spell that right?). Then use a tank coating kit for prevention. Someone made the point that gasoline with high amounts of ethanol can be hell on these tanks. They say it can create moisture in the tank causing more rust. So for now I'll just make the repairs, and save up for a nice tank.

 

Hey Sell, Please let us know how it works out,if you think I can help, PM me. eddie

 

The tnk on my 85 has been repaired for 5 years now.

Here's how it was done:

I used silver soldier and a tank "kreem" kit.

The Kreem kit comes with a muriatic acid, to which I added a 100 peice box of 3/8 nuts. Remove the gas cap, fuel tap and anything in the tank that is not actually part of the tank or it will be ruined by the solution. Tap up the holes as best you can. Agitate the hole lot. IOW, give 'er a god shake for 20 mins or so while turnign the tank over and over. Wear safety glasses and you're probably want some lax gloves too.
Pour it out and dispose of it properly. Rinse with MEK and let it sit to dry.
Grab your silver solder kit, clean up around the pin holes and solder those suckers shut. Almost as easy as soldering wires, you just need a bit more heat. Those little "blaster" style hand torches work great. Hotter than a propane torch, small and precise flame tip, and not too hot.

Now, coat the tank with the Kreem sealer. Lots of people don't like Kreem, but I've got one bike (82 nighthawk) that's had Kreem in it for almost 10 years and the 'ceptor has had it for 5 and no issues.

Your call.

BUT......

By the time this is all done, you're going to be close to 100 bucks anyways. There's just no cheap way out of it with a rusted tank.

I suppose you could buy the sealer part of the kreem kit, air out the tank and just pour it in. But don't expect it to work very well or last very long....

Good luck.

 

i know i am wayyy old on this thread but i do have a great solution to rusty gas tank.. use white vinegar and let it sit for a few days no shaking required .. after a few days empty out vinegar wash with water and use baking soda to nutralize acids and bases.. wash BSout and tada !!
