I will second the Caswell suggestion. Ethanol almost ate away the bottom of a fiberglass tank on a Norton Commando I had a couple of years ago. Scrubbed out the inside and treated it with Caswell, problem solved. My experience is that before the tank actually leaks, the first indication of a problem will be sticking carb slides and an exciting time as a result....

Hi Spud,
I got an email from Caswell saying their product was ethanol proof and fibreglass friendly so will probably use it in my tank. Am just laying up the Carbon fiber for the bottom section of the tank and ended up using epoxy as my vinyl ester test pieces looked crap. Before I join the the top and bottom together I'll give the surfaces a good corse sand to help with adhesion for the liner.

I've been reading up on this in the boat forums and they seem to be leaning towards Vinylester resin too, although no one seems to have a rock solid idea except change to stainless tanks!
The Caswell suggestion sounds like it may be a good option.

platform wellies will suit at least one shearer that's worked here. His proudest life achievement is that he's chalked a big 'SLADE' up high in the roof of every shed he's ever worked in. Rock!

Rob: I've used other tank treatments that touted they were ethanol proof, but were not. I coated my Commando tank with another such treatment, and the coating turned brown and flaked off. I filled up the tank with a box of small drywall screws and shook the hell out of it to remove the old coating, then treated with simple green to clean it, and let it dry thoroughly. Another thing about Caswell is that the instrutions state that the kit can treat two 5 gallon tanks, but how coverage should really be measured is by interior surface area, which can vary widely on two different shaped tanks. Half the kit did not give enough coverage on the Commando tank, which is long and skinny. May have been enough for a tank that is short and fat.
Had to use the whole kit to properly cover the interior surface. The stuff sets up fairly quickly, so you can turn the tank while it sets up to make sure the entire interior is coated, and after the sloshing stops, you know it has set. Many people here in the states use Caswell to repair rotted steel tanks, since the epoxy sets up like a bladder inside and seals pinholes and small fractures.

This subject is also being discussed on other forums. This one identifies ethanol levels in fuels by various distributors around the uk. Seems like it there may be regioanal variations. http://www.ducati851and888.com/showthread.php?t=3238&page=6
The attached may be useful. ok not possible to attach document entitled "Guidelines for blending and handling motor gasoline containing ethanol[1]" as it is too large. It may be possible to download from the link. If not I can e-mail a copy.

I've noticed fine grains of what look like rust in the float bowls of the Mirage, so I began researching tank lining options. I ended up deciding that Caswell looked the best -- tough and relatively straight forward to apply. However, the weather turned ugly before I had a chance to do the fuel tank. That's my project for Spring, '11 before I put the Mirage back on the road. I

After being dissapointed with the finish if the vinyl ester I've decided to go with epoxy and yesterday popped off the bottom of the tank from the mold. Not 100% happy with the result having a few air pockets in the surface and some yellowing of the epoxy in a couple of the areas where I worked it too much in those difficult corners and it sort of went foamy. I'm confident I know where I went wrong so the next one should be better. Next I'll attemp the top section which should be easier as the shape doesn't have tight corners.
As for liners, Casswells seem to be the prefered option so far.

Red,
I looked at those anodising kits and there is a lot more to consider than just the buying kit. It is probably worth a separate post to find out who has used these successfully and what all the tricks are. I know that some guys in the Qld Historic club have got it right. Having one that is sorted would be very convenient and save a lot of time. Caswells have a good help line as well.
