CAV GT Fuel vapor

I was always a bit annoyed by the fuel vapors coming from the car. After one night in the garage , it smells a lot.

I decided to re design the fuel system around the tank.

First: i switched to the new alu tank from CAV
second: i replaced the fuel caps by sealed fuel caps from Gelscoe. i also redirected the overfow fuel pipe inwards in the tube.
third : as fuel caps were no more vented, i vented the tanks on the rear side by installing rollover valves
fourth : i put a 2 II Much canister on each side to collect fuel vapor.
and now its 100% clean !

A 05.02.2008 manufacturing date on your fuel cells? Marcel, most bladder- type fuel cells have a certified life of five years. Might this be a source of some fuel vapors?

Wish I had known sooner, I have drawings for CAV tanks ment to fit No. 193, a two year old tub, if you like. If you don't mind, what did they cost?

Yes, not much to them, wont be to hard to make but a small mod will have to be made to the front end of the tub in order to slide them in. I made my own before I had the drawings and may change them sooner than later, may go with a bladder, not sure.
 
Alu tank is around 800euro .very well done , and baffled. I am selling my fuell cells, you can see ad on forum parts .
 
My CAV is an early one. I want to switch to alu tanks for the exact same reason. The car stinks...the garage stinks. No leaks that I can find...but when it has a full tanks I know it's leaking someplace. Who can I get the tanks from?

Check behind the right wheel well. Some of the early bladders tend to seep there. I replaced my cells with updated Fuel Safe cells and put in check valves in the filler necks. Absolutely no fuel smell.
