jims tank lining

Steve, looks like your getting it out of there goodly.
Just to add...my /7 Kreem job, some 15 years later now, it's good...no peeling or anything bad.

Yep, I'm shaking the empty tank vigourously after draining and filtering the sludge every day. Return the vinegar and shake it up again. The sludge continues to drain out and the inside is getting there. I'll keep it going for a few more days. The vinegar seems to work well.

Rubber stoppers I bought from Clark Rubber and Aldi has 2 litre bottles of white vinegar for $1.20.

KREEM is considered the worst of all the tank sealers. Apparently it is not ethanol-proof because it peels off within 18 months on the bikes I've seen it used on.

I’ve used the first 2 steps (the detergent and the zinc-phosphoric acid) on at least 4 gas tanks. Used their sealer on 3 (72 Yamaha 125 enduro, 71 BSA 650 and a 73 Triumph 750) and RedKote on an R90S. Haven’t had any issues with any of them since. I used the RedKote only because is was closer to the original sealant on the BMW. I removed the original sealant by filling the tank with cleaning vinegar and let it sit for a week. Most of it came out as full sheets. The reminder came out when a shaked it with a length of small chain.

The POR first step cleans out varnish from the old gas. The second treats rust and leaves a nice zinc coating on the inside.

Guess mine is a freak case since I've not had a problem all these years with using ethanol fuel.

What about using electrolysis for removing rust? http://www.instructables.com/id/Electro ... fuel-tank/
Anybody tried that?

► The vinegar is merely a very mild acid that eats away the rust. If you feel like the rust is extensive and/or you simply need to hurry the process up, then you can use diluted muriatic acid, available at any hardware store.

► The tank coating we now use at the shop is Red-Kote compound (by Damon Industries), available in the USA from O'Reilly's Auto Parts.

I did LaDonna's bike over 10 years ago with Kreem still ok.

I used Por-15 in my toaster. It's held up great with zero degradation in over ten years. I recommend it.
