Fuel tank venting Options

[FJ1200]

Morning,

I think its finally time to address the fuel smell on my 72. I pulled the tank last night and it looks like the tank was probably replaced at some point as it is near perfect. I ordered new stainless tunnel lines from Chris Foley as well as new hoses and clamps for both ends. My question is venting. There is literally no hoses left in the frunk. It looks like the 3mm lines should all tee together and tie to the charcoal canister. So 2 ports on the expansion tank, 1 port on the filler neck and the then the canister. Is this right? If so then I should need 2 tee's. The overflow hose looks like it is currently NA, 914 rubber is out of stock as are other vendors. Has anyone used 3/4" clear poly tubing in its place? Lastly after I hookup the canister does anyone offer a clean looking solution to tie the suction side into IDF air filters?

Thanks.

If your goal is just to get rid of the smell, you may be able to get by hooking the vent line from the fuel filler to a long 3mm line and running it inside the overfill hose out the bottom of the car. Just make sure that both the overfill hose and the vent line exit the hole in the floor and are not just sitting under the tank.

Otherwise, hooking the expansion tank and charcoal canister up as designed, cap the side of the canister that the fuel vent line enters and run the remaining line from the charcoal canister out the hole in the fender. No need to have the blow through actually working it just needs to not be venting into the trunk to get rid of the smell.

Thanks James (and Clay), that worked well, that being, run the hose down the overflow. I'll still work on getting the canister hooked up correctly, but this is good in the meantime.

Much appreciated, everyone.
