Default Vapor line.. Can I remove it?

I'm installing my brake and fuel lines today and was looking at the assembly manual about the vapor line... It goes from the tank to a canister in the front and then into something else which I don't remember... I know this stuff is for emission purpose and since I don't have any emission control, I was wondering if I could remove that line/canister entirely... I would just like the little rubber hose on the tank so no debris goes in. What do you guys think?

That line also serves as the "vent" in the gas tank. Make sure you use a vented gas cap, if you plug that line.

with the price of gas, why vent it when you can burn it?

Ya know... thats the line I hate most.... if it ain't broke.... my dad always say that and to tell you the truth, I think if everyone said that there would never be any improvements made in this world. Wanna stay in stone age? its working...why change it?

I capped mine at the frame with a rubber cap and have been running it with a non vented gas cap. Probably should get a vented one but if it ain't broke..... :jester

Please don't take this as a swipe at you personally, OK, cause it's not intended that way. Cool?

I fail to see how removing the vapor line is an "improvement". It's not broken, it's not causing any problems, and by removing it you will not be "improving" anything with respect to the cars funtionality, performance, or drivability. If your argument is that you don't like the looks of it, then that's cool. "Improvement" in the visual appeal is a valid reason. It's your car after all :cheers:

That line serves one major purpose as far as I am concerned, it keeps the gas fumes out of the garage. If you park in a garage it will reek of gas without that in place. To me it is worth maintaining for that reason alone. It is one of the few emission items that does a good job and does not cost any HP :)

I'd like to keep mine hooked up to keep the fumes down, but I hate all the vacuum lines they ran on the later C3 cannisters. How did they connect the cannister to the engine on the older C3's?

A functioning vacuum cannister will not rob you of power. A non functioning cannister, a leaking cannister or hose, will rob you of power (loss of vacuum). That said, it's not a bad thing to have it working. The cannister does have a job to do....

Well yeah its a visual improvement... Thats 1 canister and 2 hoses less in my engine bay. :D And sorry if I seemed a bit pissed... maybe it was my bad day yesterday. As for gas fumes, I'm sure it ain't that bad. We have 2 VTTs here which have open vents and it doesn't reek...actually it doesn't smell at all unless u plug the hose in ur nostril. :lol:

If you want to get rid of the cannister here's what I would do. Remove the cannister and cap the line at the front of the car. Then go to the rear and on the left hand side of the tank at the top plug the lines coming out of the gas tank. This will effectively eliminate the vapor system but will also give you a closed tank which has to be vented. Get a vented gas cap and you should be OK. This will allow you to run without the cannister or the hoses running to it but will leave the line in place should you change your mind later and want to reconnect it. :chevy
