Fuel line question.

[vrinner]

So I put on a cone filter and got rid of the stock air box. In doing so, there was also a canister mounted below the airbox that I removed. It has a line that goes back to the gas tank. What is this line for and do I still need it? If not, do I just disconnect at the other end

Thanks!

I would replace the canister---

the canister holds, the fumes coming from the gas tank vent ... it's probably not a good idea to have gas fumes under your hood.


I've seen people flick cigarettes into a bucket of gassoline before, but even get close to some fumes, and BOOM!!!

I removed that canister, then ran that line out from under the car somehow (I did this a couple years ago and the car is at my shop now so I can't look at it right now to see what I did).

I had the same concern about fuel vapor, so when I first did it, I checked it a lot for fuel/odors and never noticed anything.

I think that now that someone else shares concerns over it (SVOeric), I'm going to re-route it back by the tank somewhere.

Back in the old SCCA Escort endurance and IMSA Firehawk series, I saw several folks who felt an urge to mess with thins, like installing resistors in the injection loom, poking pinholes in vacuum lines, and removing and plugging the cannister line. Invariably they would have these illegal clandestine "mods" come back to haunt them.

If you're using the original gas tank, the charcoal cannister is an integral part of the "closed" system as originally designed. Teams whose cars had plugged cannister lines would develop enough of a pressure buildup that the pit crew member in charge of refilling the gas would get doused with gasoline under pressure exiting from the tank when he removed the gas cap.

The sanctioning bodies require a 1 quart capacity catch can for vehicle fluids anyways, so why not just leave it in place as designed? If you really have to remove it, route the small line to the intake tract before the air flow meter with a check valve in line. That would eliminate the fumes issue as well as eliminate the possibility of overpressurizing the tank.

It's not that I have to remove it, it's just when I took off the stock air box the line going to it had no where to go.

So if my cone filter is directly connected to my VAM, what do I do with the line the went from the canister to the stock airbox?

Find a small bulkhead barb fitting that you can bolt into the forward or rearward face of the filter after drilling a small hole. That and a short piece of vacuum hose will do the trick.

Phoenix is the track where I got doused with gas and turned into a tiki torch because the car owner didn't tell me of his "trick" mod that he did. Some folks have no business being around cars.
