AydinZ71 Posted July 25, 2020 Share Posted July 25, 2020 My 71’ has a racing fuel cell installed by a previous owner. It has two fuel sending units, a fill orifice, and a simple filter breather for the vapors to escape. unfortunately, my garage Is taking the brunt of those fugitive emissions. Any idea of how I can remedy the fumes? I was thinking of eliminating the breather, and running a hose to a carbon filter canister. No idea where to start looking for one. Anyone have any clever solutions in mind? My background is thermodynamics, but fuel tanks are not my speciality. Quote Link to comment Share on other sites More sharing options...
grannyknot Posted July 29, 2020 Share Posted July 29, 2020 I would start at the wreckers for a carbon canister, just about any car from the 80s. Can you plumb the tank breather up to front and into the air filter? You might install a ballcock valve on the breather and close it when you put the car away in the garage and open it again after start up.

Ironhead Posted July 30, 2020 Share Posted July 30, 2020 I am using one of these on my build: https://www.iimuch.com/ I cannot say if they work or not, since my build is not finished, but they claim to resolve precisely the problem you are talking about....

Whitley_280z_2+2 Posted July 30, 2020 Share Posted July 30, 2020 I followed @grannyknotsuggestion. Spent $10 on a canister from a Miata at a junkyard. It makes a huge difference with the fumes! 1 Quote Link to comment Share on other sites More sharing options...
AydinZ71 Posted August 8, 2020 Author Share Posted August 8, 2020 Pretty cool! Nice solution I ended up getting two fuel line check valves. One will be to release pressure from the tank, the other is for vacuum. Both have a light spring pressure they have to overcome, so they will isolate the tank up to a few inches of mercury in either direction. You can see my proposed solution @240z_restomod Quote Link to comment Share on other sites More sharing options...
DREW RBZ Posted August 10, 2020 Share Posted August 10, 2020 I used the iimuch system. Completely eliminated fuel odours. Not cheap but an awesome product. https://www.iimuch.com/ Quote Link to comment Share on other sites More sharing options...
