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.
 
I'm ordering 2 new alu tanks from CAV as well. Are there any other ways to make the fuel gas cap from 'venting' to sealed? I see you bought some from Gelscoe, but they look like 'regular' aftermarket caps somehow.
Also, from your 2-much canisters, where do the vapours go? You route them to some place, or just in your engine bay.
 
Jasper, if you don't mind, what kind of time frame and cost did CAV give you? I could make my own for the cost of the freight to where I live and be on time!

I'm in south-africa myself.. that kind-of helps with transport cost. They charge 750dollar (equivalent) each, and modify to EFI/return system with balance line when I send my car there.
