TD in DC

I want to put a breather filter on the line that vents from the gas tank. I would like to get it out of the engine bay and vent it somewhere near the rear of the car, but I have been having a hard time finding an appropriate filter locally.

Can anyone point me to an on-line source of the right type of filter to buy?

Thanks,

TD

auto zone usually has stuff like that. I did the same thing aswell, you can also take out the metal line that goes up the firewall and the plastic line under the car just pulls out.

I actually was looking for this exact part among others yesterday at my FLAPS. No dice.

They had some random stuff but nothing that would work for this application. The main question I have is whether the flow needs to be two-way or one-way? IE, does it need a regular breather filter or a check valve?

or you can plug it and get a vented gas cap like i did, If you put a filter under the car it may leak since it would be lower than the tank now that im thinking about

Is there any down side to this whatsoever? If no downsides, this seems like the wisest solution.

I never noticed any negative effects

Actually, in reading about this, the gas cap is supposed to vent only when the pressure exceeds the amount that normally would be filtered through the charcoal cannister. hmm.

venting hydrocarbons to atmosphere... boo-hiss

20 year old busted charcoal canister = was already hissing. It's a race car anyway...

Oh yes, and I still plan to vent mine in the same spot where the charcoal canister was originally...

I typically vent much more after steak and beans.

What do you guys think about this option? http://www.speedwaymotors.com/p/451,...Tank-Vent.html

Lemme ask you this:

Doesn't the factory fuel vent line already have something to prevent fuel from entering it at the tank? If there wasn't anything to prevent fuel from entering the line, wouldn't the line fill with fuel when the fuel sloshes around in the tank?

I asked this question last fall, and no one responded. Is the filter to keep debris from getting INTO the line, and thus into the tank? Or is the filter to keep fuel from spilling OUT OF the tank (ie check valve type thingy)? Or both?

Jim, I don't know. I assume that the tank needs to be vented so that the car will function properly. The original function of the charcoal cannister was to keep the air clean and make sure that the car doesn't smell like gas due to the venting. When you remove the cannister, I assume that (1) you want to keep the vent clean so that it doesn't plug (e.g., spiders) and cause the car pressure problems and (2) you need to do something to prevent the driver from smelling gas fumes.

I wonder whether the valve I posted would do the trick since it is a vent for a race car fuel cell.
