Are lightweight plastic Fuel Tanks illegal ?...

I have searched this forum and i can't find any mention of an aftermarket lightweight fuel tank (perhaps made of GRP or carbon fibre) as a direct replacement to the standard fuel tank in the same position ?

I'm looking for the lightweight options to replace the fuel-tank, prop-shaft and exhaust on my VI

Is it illegal to have a non-steel tank under the car, is that why there are no lighter options to the standard tank position ?

cheers guys

Ren

Don't fancy using a GRP or carbon fibre fuel tank on any car. Too easy to split and tear open in an impact. Plastic tanks are fitted to a lot of cars these days but i think they have to be approved and tested as part of their type approval.

If it's weight you're trying to remove, use a basic alloy tank in the boot with the swirl pot integral below, cuts out the need to plumb in a swirl pot and pumps, plus you can avoid surge, even with only a few litres in the tank

Ah interesting !!

Well Kieran i'm trying to achieve as much lightening as possible with these heavy Evo's

Sounds like there is nothing which is much lighter to directly replace the standard tank so i'll leave that alone and change some other stuff instead

I may, at a time further down the modded line, change to a alloy tank in boot type set-up, but not yet !

thanx for the input guys, love the work u done to your evo's and pugs coskev
I used to have the legendary 205 1.9gti still miss it to this day !

you could reduce the size of the tank half it down etc etc takes a bit of fabrication
