Fuel cell venting and fumes?

[69MACH1]

My 69 Mustang has a fuel cell, I am tired of smelling like gas every time I drive the car. Yes the fuel injection is a bit fat and that does not help, but I do get fumes into the car from the fuel cell as well. The fuel cell is vented out of the trunk to the very rear of the car behind the valance near the license plate with a little filter on the end. I was thinking of putting some vacuum on it from the engine in a way similar to "smog" equiped cars are. I envisioned a hard disc brake line running under the car from my vacuum accumilator into a fume recovery cannister near the fuel cell. Does anyone have any advise or experience?
Thanks

I plan to run a vaccumn canister from an s10 mounted near the Fuel cell and plumbed back to the motor. Funny i need to also find a plumbing diagram for this.

Here are a couple quick links for you.

Thank you for the info. Do you think it is better to run vacuum back to the rear of the car with the charcol canister wherever it fits, or the opposite way with the canister at the front of the car, in the front wheelwell. Also do you have an idea what would be the proper i.d. tube to run to the front of the car from the fuel cell, dependent upon whether it is vacuum or vapors.

I am/was wondering the exact same thing. I am still researching this and when i figure something out i will post it. I was also hoping someone on the Forum will be able to help us with this question.

PS Currently i am planning on mounting the canister in the back adjustant to the tank. I plan to lift my test mule truck up in the air and see what size all the factory lines are and just duplicate those.

One of the fuel cell compainies sells a valve that holds back three or four psi on the cell, that prevents most of the fuel vapor from escaping. There are also valves like that for boats.

here are the diagrams that were put up on syty.net for the syclone 4.3 turbo

after doing as much research as i could i plan to mount the can in the back.

I went to the junkyard the week before last to see what I could find in the way of charcol canisters. I found one from a 71 Mustang and another from a Triumph Spitfire. Both were mounted in the front of the car but opperated differently. The Ford canister has a small diameter connection to the fuel tank and large connection to the air cleaner housing. There is no vacuum connection, and other connection. The Triumph canister had a couple of inputs on top and a large vent on the bottom that was connected to a solenoid that vented the cannister to the atmosphere when the car was not running but connected to vacuum when the engine was running. In my car there is no room in the engine compartment for the canister but there is a nice place that I can place it next to the fuel cell. Attached are two addresses for photos of the two canisters. Hopefully I will be able to get the Triumph unit installed the week after next.

I installed the charcol canister a month ago, what a difference! No more gas fumes in the car, especially when I fill up the car. I do not know why I did not do this when I first bought the car. If you have been thinking of it don't put it off any longer.

My buddy has a similar problem in his 70 Chevelle, though its carbed with a tank instead of a cell. He says it stinks the garage all the time even if he hasne't started it for weeks. Any thoughts? I told him it might be his braided line sweating fuel and causing the smell. You do you guys think?

I have the same problem with my Fuel Cell. Car hasn't been started in two weeks, but has a strong gas odor when you go into the garage.

Do you have steel braided line? most likely the cuplrit IMHO.

It's called permeation. Braided hose "Sweats" just enough to generate fumes but not enough to leak. Replace as much of the braided line as possible with hard line. Russell hose is the worst.

I do have Braided hose running from the fuel cell to the front. I guess I will put it on my list to replace. Thanks guys
