I just bought a very nice 66 Spitfire Mark II from a collector. Won 100 points at the AMCA show in Vegas 20 years ago. Has 32 miles on a rebuild. Hasn't run in 20 years. Tank and carbs were drained and been stored inside in a climate controlled building. After changing all fluids I put in 1 gallon of gas ( E10 here in California ) came back 2 hours latter to go for my first ride and gas was dripping from the lower right front seam of the tank .
I did not know of the issues with ethanol gas and fiberglass tanks .Learning a lot on line . Looking into repairing the seem and coating the inside of the tank .Which most forums claim is just a band aid.
Does anyone have good experience they can share with me ? Also what about a RELIABLE source for a metal tank ? All i see online are ones made in India which everyone says to avoid! I have an e mail into British Bike Bits to clarify their tank source as the fine print says " foriegn made".
Have to think there must be a solution to this problem rather than just trying to buy ethanol free gas, which is impossible in lower Ca. or finding someone to sell me aviation fuel. Any feedback would be appreciated.

Chances are, that tank was delaminated when it was restored.

Personally, I have had good luck with KBS Coatings Tank Sealer kit. It is a urethane based sealant and will flex with the tank. And it does work on fiberglass. Some coatings don’t. Downside, KBS has VERY specific instructions that have to be followed to the letter. No short cuts. Ever.

If you are gonna ride it, the least hassle may be an Indian tank. Keep the glass tank for show.

Scott, reading your post, sorry to hear about the leak. Was the bike still in it's 100 point condition or close? Did the paint get damaged which is likely? In my humble opinion you really have no choice but to repair the leak and get back to the wonderful condition of 100 points or near. Here is a link to ethanol free gas in the U.S.: https://www.pure-gas.org/

Those Holt Works tanks look great. £515.00 GBP currently equals $624.00 USD, which isn't going to break the bank and is a great investment for a regular or somewhat regular rider.

Thanks to all for the great info. Rich- I'm going to order the sealer from KBS and of course follow the instruction. Andy- Holtworks looks like the quality steel tank I am looking for so I'll order a 2 gallon tank from them also . Bustedknukel- I had previously found the pure-gas site. Nothing near me though. No paint damage on the leak as it was from the bottom seam. The bike was 100 points ( came with the trophy) until I just replaced the tires on it, " Made in England" Dunlap K70 with new K70 but not ribbed on the front . Same tires I use on my 72Triumph Tiger . Suits me well putting around the back roads and mountains of SD. I guess now it's 99 points. But i'm keeping the old ones.

Those tanks are aluminum tanks.

I have a Greeves fibreglass tank on the shelf at work, it has never had ethanol fuel in it as I bought the bike before ethanol was added in the UK. It would never hold any liquid. it is porous and mushy. Fibreglass suffers from vibration, sunlight and variations in temperature.
It is easy to blame ethanol for all the wrongs in the world

If you think it is a mess now…….add ethanol.

I feel your pain. MY 67 spitfire did the same thing. I literally poured red chunks of fiberglass out of my tank. I have used Bill Hirsch sealer with much success. Ok for fiberglass. DO NOT use red coat!!! The band-aid comment is true. I purchased a steel tank from Randy Baxter. It came sealed with the POR stuff. It does not have the reliefs for the graphic on the side of the tank. Not a big deal for me. Don't know if he still has them though been a couple of years. I am pleased with it. Good luck!!

For many years fibreglass tanks were banned in the UK, a container full of fuel that could (and did) fail without warning sat above a hot engine and high voltage cables. A mobile Molotov cocktail

"If you think is a mess now…….add ethanol."
The reason I am having an alloy tank built for my Rickman is 100% methanol fuel, now that does dissolve things

My Bill Hirsch lasted about 6 years......but the tank had already been leaking when I sealed it in the first place. What I did like about the Hirsch product was that it washed out with acetone. That was several years ago......not sure if they've had to change the formula to keep up.

I've given up on fiberglass.

I used KBS in my Dunstall tank and it failed. I then tired the Hirsch sealer and it held up well. What I liked about the Hirsch is that you can re-coat if needed. I re-coated after 2 years for extra insurance and it has held up well. I have since stopped using the fiberglass tank. I hear good things about Caswell sealer on fiberglass tanks.

I have a slow leaking Indian tank, fixing it is on this winters fix it list, along with new wheel rims.

It apparently started at the seam in 2015. looks bleedin hideous.

I had the same problem with my '66 fiberglass tank. with a dremel and a small mill/drillbit (<2mm) I've cutt out all of the seams. so where the top and bottom half are epoxied together there's a seam, this seam is dremeld out from outside to inside of tank, then I've resealed this seam with cloth and polyester. 10" at a time.

works great, I can have 5%alcoholfuel in my tank for days without leaking

I've had good success with Caswells epoxy sealer in multiple glass tanks. Correct preparation is important.

Ethanol will disolve polyester and vinlyester resins. That is what the original tanks are made of.

For original glass tanks to last, they need to be drained of ethanol laced fuel after riding.

Glass tanks are not for everyone, as they require an additional level of care.

Gary...........I think your "......need to be drained of ethanol laced fuel after riding".......is the key. Well, that and proper prep before sealing.

I'm curious though........did any of the tanks you've successfully sealed have an ethanol related leak/problem before you sealed them?

One did, the Firebird Scrambler. Really gummed up the carbs. Since sealed, no issues. Some of the others had leak problems, but don't know if they were related to ethanol or not.

The most recent tank restoration, the '65 Spitfire Hornet, as posted on the Hornet etal thread, was real soft inside and resin starved with significant leak problems not only along the seam but also on other bottom areas, so it will be a good test tank for the sealer.

Thanks for the reply Gary. I'm going to write off my sealing failures to bad prep. My Hirsch liner lasted for 5-6 years....with fuel left in the tank. But it finally failed. My attempts with Caswell didn't last long at all. I was wondering if some of it was because of the ethanol damage happening before re-sealing......but your results shoot that idea out of the water.

I've got a couple of NOS glass tanks and several used that have never been sealed......or had ethanol in them. I'm not completely giving up on them.....somebody might use them one day.

For me it was just too easy to switch over to metal since that's what BSA did.......so the swap doesn't look out of place.

Thanks again for going to the trouble to reply.

Gordon
