Removing charcole canister

stinky jinx · Apr 18, 2005

Hey Gang,
My 72 Camino has a charcoal canister that I want to remove. It has three hose's that attach to it .On goes to the to the front carburetor vacuum port. One goes to the PCV port on the valve cover. And one goes to the gas tank ( I believe it is to vent the tank) I did try to remove the canister once. I plugged of the carb vac port, took the plastic tee out of the hose going to the PCV port ( I ran the other part of the tee to the back of the carb) And plugged off the hose that ran to the Gas tank. That is where the problem started. Since the tank was no longer vented ( I'm guessing), the fuel pump could not pull the gas to the engine....engine no go!

My question is...If I use a gas cap from a earlier Chevy ( the caps were vented)
will this cure the problem? Or is there more to removing the charcoal canister than that..... If so how do I do it correctly?..............jerry

gas cap

The line from the pcv goes to the carb. This eliminates 2 hoses. The vent line to the tank can be plugged off with a bolt. Remove canister. Buy a replacement locking gas cap for your model of car. The key hole acts as a vent.

The line that goes to the tank is the actual vent. An open fuel cap may not vent unless the small vent tube is next to the gas filler tube.

Either change to a '71 setup (or whatever year GM didn't use EVAP) or keep the vent line open by inserting some type of small air filter into the line (such as a rear end housing vent).

i did this on my 82 Grand prix, i drilled a tinny hole in my gas cap for vent.. the tank would pressure up otherwise and when i undid the cap i would hear the gas tank going back into shape

Just curious....

if it aint broke why bother? The canister does not hinder preformance in any way....why cause yourself the problems?

Well to be honest....

There are three hoses that run over the top of the engine, and I just want to clean up the engine compartment.......just clean and simple........jerry...

Jinx,

If I read your previous attempt correctly, you were applying vacuum directly to the tank. With the engine pulling vacuum and the fuel pump pulling fuel, I'm surprised you didn't collapse the tank.

I agree tm454, but if you're intent on doing this, have you tried just removing the other two lines to the cannister?

AND WHAT THE HELL IS WRONG WITH A RED RAG???

okay i'll stop yelling. i have a 72 with the same thing. i'm just gonna leave it on my inner fender. its a strange set up no doubt. and it's kinda stupid to have a black coffee can under the hood. might be a good place to cook a burrito. also, some of those little rear end vents have a check ball in them so it would be sucked in and wouldnt work if you use it.

I don't get the Red Rag thing bull...what gives??

A clean look is nice too but.......it wasn't broke and you broke it trying to fix it....jerry??
