Removing charcoal cannister

[87Regal3.8SFI]

Thinking of removing it to make more room. I am wondering if it's safe to connect the two lines from the cannister together? Or will this affect anything?

Also I have a Turbo Tweak chip, perhaps the ECM won't throw any codes?

Thanks1

No codes will be set with it gone but not sure about your lines, I will put a small filter on the tank line when I find one that fits.......but it has been off and open for a while.

I was hoping if I tied the two lines together, yet kept the check valve, then not at boost the engine would draw the excess fumes and burn them but in boost the tank would not be pressurized.

Not sure if this would work or not. I wouldn't want to leave the tank line uncapped though.

easier is just move the canister to the frame rail by the powersteering box or even under the fender liner

if you remove the canister cap the vac line.
as for the vent line ...dont hook the line to a vaccum source and dont cap it ! you need it to remain open to prevent tank pressurization and to also allow air to get to the tank so fuel can come out. you can get breathers for the hose from 4x4s (usually clipped up on the fenders) that will allow venting but not allow bugs to crawl in

That is where I have it now but it gets in the way of my K&N plus I can only use one tab to keep it held down. I would leave it but I am seriously considering just cleaning up the engine bay some.

Don't just pull the cannister & leave the lines laying loose.

1 line is vacuum, the other is a fuel tank vent. Hooking them together would not be advisable.

I moved mine to the original location of the crossflow muffler & properly wired it. I have now installed a third (crossflow) muffler & again moved the canister, it's now between the rear bumper & the fuel tank.

I had considered only running the vent line to somewhere near the back bumper (maybe near the fuel fill area), however I felt GM put it in the car & I was able with very little effort, to retain it.

Coupla years ago someone posted his results. The insurance company was rebuilding his garage & house, but the GN was a loss. He had left the vent line laying on the frame in the engine compartment.

I put a bolt in the upper vacuum line and then a cheap filter in the vent line.

I've heard similar bad stories.

I have a 9" K&N crammed next to the canister, you should be able to figure out a way to get it all to fit. It is held down by two screws, take one out and let the canister pivot out of the way. Don't leave it completely loose don't want it to be able to flop all over the place.

Could also trim your MAF pipe shorter and then the air filter wouldn't be as far over.

[87Regal3.8SFI]

The filter is currently secured onto one end of the MAF, I think I'd be better off to get an extender of some sorts. I was going to purchase an air filter relocator kit but at the time dont have the extra $279 to burn.

I had intended to use the line going to the cannister off the engine to run the boost gauge once the check valve was removed.

What's wrong with capping both of them and using a vented gas cap?

Relocate the cannister under the fender liner. You can drill a hole in the bottom of the sunken area directly under the current cannister position. Then if you ever went back to stock, the hole would be covered. Run your solenoid wires and the hose through here. You can secure the cannister with a couple or 3 large hose clamps connected in series to wrap around the cannister both top and bottom. Cut two slits in the fender liner to run the clamps through, then strap them around the cannister and cinch it up tight. Cheap and easy.

Frame rail is the easiest way to go. Look at picture! Attaches with the two factory tabs, just have to drill holes. The little alcove in the fender well almost makes it look like that is where it should have gone in the first place.
