That is exactly what I have been thinking....along with biting the Bullet and ordering a tank from Burton's. I would like to keep it original with a FB tank but I guess Steel would be a lot smarter move since I plan to repaint back to original color.

I'm waiting for the "I told you so" :lol:
If Burtons suggest new GRP tanks which are supposedly ethanopurposel proof need to be sealed before use, they are unlikely to be able to help with any sort of guarantee, and I think it would not be that sensible to buy a GRP tank which isnt guaranteed fit for
So what is the correct resin and process?Carbonfibre said:There is no problem whatsoever making GRP tanks which are fully resistant to any commonly available pump fuels. Underground fuel storage tanks made of GRP have been in use for decades without any major problems, following the change to Efuels.
However production methods need to be modified to ensure success, when motorcycle tanks are made using the same UL specified resin systems as used to make the underground storage tanks.
The failure to alter production processing even though the correct resin systems are being used, is likely to lead to corrosion in some cases, and is a very good reason why any GRP tank that comes without a guarantee should be avoided!

Seems easy enough, why isn't anyone doing this?Carbonfibre said:Novalac vinyl ester resin, with very careful attention paid to the exotherm achieved during the cure process, and use of a chemical resistance layer applied according to resin manufacturers data sheets.

Actually, there is. My friend Dave Ashenbrenner, who lives in Florida and goes by the eBay handle "neuxstone" has been making ethanol-resistant fuel tanks for years now. Very elaborate process of CNC crafted molds combined with a hand-layered process that enables him to offer a variety of tanks. I sent him a crappy, but original Dunstall tank that Dave is using for a mold so that I can have a back up if / when mine decides to fail in the future. Here's a link to one of his tanks. I don't have a link handy for his actual website where you can read more about his process....I'll look for it this morning and post it later....or you can email him directly if anyone has any questions for him
