Yea here is a couple of pointers

The ACU has a general rule with parts used must be deemed to be safe. So turning up at a race meeting may only get you as far as scrutineering, if the Technical inspector doesn't thinlk its safe then he can fail it

The FIM rule on fibreglass or carbon fibre tanks requires the manufacturer of the tank to prove it to be safe.
Now I know our Cheif technical officer holds a FIM permit and carries the FIM rule book with him and having chatted with him about it, I would say he doesn't want tosee thm out on the track unless they comply with the rules as laid down by the FIM

Carbon tanks aren't cheap so not really in keeping with DD, Fibreglass tanks can be made for less but having a decent one made that is safe and impervious to the effects of some of the chemicals found in todays pump fuel isn't going to be cheap.

Seems a complete lack of fibreglass tanks from the likes of Harris Performance, Demon Tweeks etc.

Mainly because the only way they can prove them to be safe in the event of a crash and possible rupture is to fit them with an approved fuel cell.

Be cheaper to Buy a couple of alloy tanks
