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.

@914sgofast2

Everything you posted seems rights. There is minimal surface rust at the 4 points that contact the felt pads. I gave them a quick rub with a scotch brite and the steel is solid.

I think I have my answers, I need to put in an order with Belmetric and Autoatlanta and I think I'll have everything I need to put the system into a functional condition.

Thanks everyone,

I realize this is an older post. I've been searching everywhere for correct vent lines. Thought I'd ask if you were able to get the hoses/lines from somewhere? If so, where? PO didn't reinstall the cannister or any lines. So I've been trying to get it back together.

Thanks,

Quinn,
It depends on the year. Pre 74 had big lines that ran under the left rocker panel and the canister was mounted to the top of the fuel tank. Somewhere in 74 they moved the canister into the engine compartment and ran a small vacuum line in parallel with the fuel lines to connect it to the tank.

Finding the early lines requires finding someone parting out an early car. The later ones can be done with hard plastic vacuum line you can get at FLAPS.

Hope that helps.
Clay

Thanks Clay, '73. Need the big ones. May move it to the engine compartment if I can't locate some correct lines. Search continues.

Much appreciated

There should be holes for them on the inside of the left front fender, and in the engine compartment lower left front corner. They are not one piece, they are multiple pieces, and grommets for all the body pass through points.
