Nice one i'll have to drop him a line at some point with some dimensions. Problem for me really is I should have put my roll bar braces farther out to make getting a tank in a bit easier. I was thinking of putting it above the diff cage but it'd have to be mega short to allow enough space on top for the filler neck in which case it wouldn't really hold much fuel.

These tanks for drag racers must tick most of the boxes and come in all shapes and sizes.

WHat if i made my fuel tank from fiberglass(GRP) ? using a special resin (petrol rezistant). It holds petrol for more than 2 months whith no problems at all .Let s be honest...in case of a back hit no tank can rezist .

I am not so sure about the stuff for a tank. I thought f/g was banned for bike tanks but cant find anything on it, this is worth a read http://www.beyondfossilfuel.com/etha...ass_tanks.html

so under the IVA ruling, am i led to believe that the tank design in the book is unsatisfactory, or is it just a case of proving that the tank has been made to the book spec?

I used the Jazz tank for the race car I put together for Teamtrain and it was the dogs bits.no certification would be problem for IVA.
