Fuel Tank Vent

[hrosenthal]

It looks like FFR changed the fuel tank vent from a single plastic vent to two pieces. One plastic piece that fits into the tank, and another metal piece that screws into the first plastic piece.
Has anyone else received these parts. I just want to confirm before installing.
Thanks

Hey hrosenthal,

Will you put up a pic of your new tank vent? I looked in the FFR catalog and did not see it. It must be just for the complete kit. It might help to ID it better.

Thanks, WEK.

The one I've seen before was all white plastic with a dome shape top

That is new.

I have that white ABS plastic peice I found which I think is OEM. The metal part is a check valve. Right? So you still need the filter portion that many have fabbed or it will leave a strong gas smell in your garage. Thanks for the pic hrosenthal. I will eventually change mine that runs all the way to the engine bay. What a PITA!

That's interesting. How would someone go about fabbing a filter? If it's an OE part, wouldn't there be an OE filter?

That two piece part is exactly what I have as well. As far as a filter, I constructed mine out of 1 1/4" x 8" of PVC tubing. On one end glue a permeate on in which was fitted with a barbed fitting sized for the flexible vent line. The opposite end I glued on a 1 1/4" slip x female adapter. An 1 1/4" male plug gets screwed into that. The male plug gets drilled with many 1/4" holes.

The whole thing gets filled with small charcoal "gravel" from a pet store. I wire tied mine to the metal gas fill tube so I could get to it once a year or so to change the charcoal out for new.

I maybe able to post a picture later today

Used it on two builds and about to do it on another---no fuel odors (and believe me if there were my wife would let me hear about every time she walked into the garage!).

Cheers,

I think I can handle that, but I'm wondering if a regular fuel filter would work.

Another vent cannister for your consideration. Pretty much the same as what has been shown - piece of 2 inch (?) PVC, couple ends caps (one glued and one threaded in case it ever needs to be removed), "breather holes" in the topmost cap, brass fittings and hose to fuel tank vent. Filled with aquarium charcoal in a bag made from a "knee-high stocking" with Scotch bright "pads" above and below inside the PVC pipe.
Simple - and should absorb a wee bit o' fuel vapor when the car is sitting, and allow it to be sucked back into the tank when running.

The charcoal has odor absorbtion properties; a fuel filter does not.

I had a fuel smell when my car was in go-kart (after i ran the engine). After I put the body on and had the engine dyno-tuned, the fuel smell went away. I'm not running a charcoal canister (yet). Not saying I won't, but why fix something that is broke? Wait and see if you need it.

Cars were around for many years without charcoal canisters. They simply had a rubber hose vented to atmosphere. I put a plastic lawnmower style fuel filter on mine to keep dirt out. Unless you rig up a purge system, charcoal will saturate and stop working. (I just saw that Bill mentioned an occaisional charcoal change) I saw a slick looking one on the other forum made from an aluminum water bottle.

I read up on this and it seems that most people don't have an issue. I reserve the right to put one on if my garage smells like fuel.

Five years running without any fuel smells.
