Just did a swap to an LS1. I had to remove the evap can in order to make room for the engine. It will not be smog tested so I was thinking about just leaving it out. I know it would be best to make it fit, but it's just not going to.
Anyways, I have the fuel tank vapor line just hanging now in the engine bay and need to do something with it.

If I had a vented gas cap, could I just plug the line?
Can I run the line right into the intake manifold?
Can I just put a small K&N filter on it? I just don't want the fumes in the engine bay.

Anyother ideas? Thanks for the help.

 

Vented cap and plug/remove the line is one option.

Putting the vapor canister under the fender is another.

4th gen tank with the vapor system on it is another.

 

All the lines, canistor, and junk on the tank disappeared from mine.
Make sure you leave a vent line on top of the tank so air can escape when you put gas in it.

 

Thanks for your help. I think I've got it figured out now.

 

on my evap line i just put a filter on it but while driving apparently it leaks gas out of it. What would cause it to do that and would plugging the line and putting a vented gas cap fix the problem?

 

hey man i got a question i kept my evap line in my ls1 swap using third gen tank and now wondering do i just connect the plurge value line to the canister or just remove the canister and hook it up to the line on the passanger side.
