Petrol Tank bubbles/blisters

[Chris Canning]

Rather funny the various site's I use have all started talking about fuel/ethanol/plastic tanks in any order you like.

I have had a major problem with this and tank was completely distorted and covered in bubbles. A bike mechanic mate of mine has had a couple of Truimphs where the tank has just suddenly started leaking and then it's finished. It's all down to ethanol as far as I can find out. Main solution is to use premium fuel such as BP ultimate. There is a tank sealant from a Royal Enfield part place which a friend of mine uses on his fibreglass tanks which have an even worse issue with ethanol. http://www.hitchcocksmotorcycles.com/search?function=search&searchterm=sealant&x=30&y=11

No problems with the Tigger but the tank on the Sprint ST that I had before it had swollen and was a pig to re fit after removal.

T, Your right! Ethanol is a huge concern in the boating community, any of the older boats like Bertram, Hatteras and Blackfin that all had factory installed fiberglass fuel tanks have to be replaced with aluminum tanks. Unfortunately most don't realize until it's too late, the tanks coming apart ruining gas motors.
Ethanol is one of fiberglass's worse enemies!

The previous owner of my Girly had the tank repainted and the tiger stripes air brushed on which solved the problem.

At under $4 a gallon  I could stand the stickers peeling off

Even in this thing it was like driving around for free.
