Ethanol proof liner for steel tank?

Clean it out with citric acid or phosphoric acid and then look after it, no liners as they eventually fail, either through being only resistant to ethanol not ethanol proof of not being applied correctly.
 
Once clean and no sign of rust , there are products/additives like K100 , Lucas etc. that supposedly help with the ethanol issue ... no experience just from reading their product info .... I do use the K100 as a stabilizer during storage and it works as claimed ....
 
Mine is doing great after the 3 day electrolysis treatment I subjected it to a few months ago. Never did P&O it with the citric acid because it looks like new inside. Up to that time lining it had been on the table.
 
I don't have a problem with ethanol destroying my lovely roadster tank . I take it out before putting the petrol in the tank. ;)

The point is, he has a pinhole leak, which he believes to be due to rust. Of course, if he fixes the pin hole, how long before the next appears, and the next, ad infinitum.

So, his thinking is, a good and strong epoxy liner would ‘repair’ them all. And keep his current beautiful paintwork intact.

It’s a 1930 sumthin’ Rudge, and tanks for those don’t grow on autojumble trees...
 
Seems as though its time for someone to come up with a plating process for old fuel tanks. Ever talk to a plating shop about it?

(It would of course ruin the paint)
 
For New Zealand petrol which does contain ethanol a friend treated his BMW tank nearly 10 years ago with POR-15. No trouble so far.

The motorcycle kit is three steps. 1 Cleaner, 2 etch and stabilise rust, 3 sealer.

I did it on my roadster tank 6 months ago and no problems yet but that is not really a long enough test. But 10 years on a BMW tank is a good test.

But you must follow each step carefully drying the tank out for DAYS in the sun or a heated area. I put a vacuum hose in after the etch step for several hours to help airflow and then in a heated place for another couple of days until it was very dry. After the final step of sealer leave the tank for a week in the sun or warm place before putting gas in. You need to protect the paintwork from the etcher.

You must follow the instructions to the letter.
 
I did my Triumph tank with POR15 almost 20 years ago. It's had ethanol gas in it every day since. Looks like new. Follow the directions and make sure the tank is completely dry before the final treatment. Use a hairdryer or heat gun. I let mine cure a month before I put gas in it. I've also use Caswell and Bill Hirsch liners with success. I didn't really like the Caswell because it is rather thick and makes coating the tank evenly a bit more difficult. The Bill Hirsch liner is kind of thin not sure how well it would fill a pin hole. So yeah, POR15.

That Triumph experience is very encouraging thanks. The manufacturers recommend a minimum of 5 days cure I think. I did 7 days but a month would be a great idea.
 
Got mine from Frost, not the cheapest but has kept me knocking, as said you must follow the steps, and drying out is the most important.

Oh big mistake.. I didn't see you were in England. :eek:

As a New Zealander I'm not talking to you this morning ;)

(For the North Americans - look up 2019 World Cup cricket results the match finished a couple of hours ago :(:( )

Well it’s about bloody time innit?!

Our Americans cousins don’t ‘get’ cricket John... Hence they invented baseball... which is called Rounders in England and played by schoolgirls...
 
Unfortunately I'm more a football and cricket fan.

Next time !!!

Not for me, but a friend who has a rusty tank. Any advice ?

I used Caswell epoxy to line mine years ago when Roadster tanks weren't available. A previous owner's angry wife had beaten the tank with a pipe and the body shop that pulled the dents recommended lining it in case of stress cracks. No problem with American ethanol gas at all.
