DONT HASSLE THE HOFF

Ok, I did the *search* already but the explanations seem a little vague to me....

I was cleaning my engine bay and re-routing some vacuum lines on my car and thought it would look a little cleaner with the canister out so I took it off.... Now, I would like to know what to do with the open line that emmits the fuel vapors. Do I just leave it open to atmosphere, plug it or put something on it?

Thanks-

DO NOT PLUG IT UP!!!!!

Use small fuel filter, or small air filter at the end of it. This fuel pressure release line is crucial for proper fuel storage and operation. Otherwise, you'll be fine w/out the canister.

Thanks Monster! Can I use a filter like for crankase venting (small K&N) or and air filter like what comes with the HKS boost controllers?

Why should you have to put a filter on the open line if it's only venting? I just put a piece of hose on it and put it down through the hole where it normally vents. Just make sure you plug the line that normally runs back to the intake manifold.

Anything to prevent debris from going into the line.....and to break down the vapors......you dont want any major vaport exiting right into your hot engine bay. Keep the tube pointed behind the motor, facing the rear of the car.....

K&N is fine.....or just a small cheap inline fuel filter from PepBoys.

Is there any performace value of removing the canister. I know on my car (98 Jetta) there wasn't. I would assume it would be the same with a Supra. I had to remove it to get the IC in. No offense, I think its kinda silly to remove it if you can keep it.

Canister is used to filter out excess oil/fuel vapors and lower "environmental damage". Carbon material inside breaks down these chemicals, and keeps the contaminants in check. Its used for emissions purposes only. No power gains.
