A question on a 2002 T/A it looks like a fuel line and a vapor line at the engine (tied together with foil tape) Can that vapor line that also goes to the intake manfold be removed ? How can this be done? I want to use a single fuel with the corvette filter/reg.

It's possible but there are other things that need to be addressed when doing it.

You will throw codes for the various parts of the evap system. They can be turned off with tuning.

I think another side effect would be fuel fumes if your car is parked in a garage.

That evap line runs back to a canister on top of the fuel tank. I'm pretty sure it's a type of charcoal canister to absorb the fumes from the vent in the tank.

Capping the hard line under the hood may stop this. However I don't know if there would be a pressure buildup that could cause that cap to pop off.

I'm also not sure on how much the evap system has to do with venting the tank for re-filling with gas.

Thats all I got. If any info is out of wack, feel free to correct me.

You can seperate those two lines and eliminate the vapor lines all together..You can have the thing edited out of your PCM just like getting rid of cats and so forth..just cap the line and the nipple on the intake and do the edit...

I ripped mine out and just capped any openings that were left behind. Getting rid of that little solenoid looking thing by the intake really cleaned up the intake area as well.

I want to know about this also thought about removing mine if its not too much trouble or doesnt cause a lot of extra fumes. Still want the tank to be able to vent properly.

i removed mine all the way to the tank..theres a hose hanging from the tank on my lt1 with a filter thing on it that i believe is what eats all the vapor smell..i blocked the line going to the intake all the way back at the tank..removed the charcoal canister...left the little yellow breather and that line intact...no fumes here...
it dangeling near where the ebs and fuel pump sensor plug in at..

I used my EVAP line as a return line. When I did that, I unplugged the plastic line coming from the tank that goes into the hard line that goes along the frame rail and into the engine bay. I left the plastic line just hanging there for the vent. I leave my car parked in my garage all the time, and I've never noticed a fuel smell. I would not however just cap it and forget about it. That would bug me all the time knowing there is nowhere for the fumes to escape if the pressure increased in the tank.

i have heard of people using the steel line under the car as a nother fuel source. but does any one have pics. it would be nice if someone could go a complette write up on this on how to do it right. i don't want fumes. i would love to get rid of that peice. and if i go with another fuel line like a -8 can i really delete it and forget about it.

I agree a write up would be nice I dont know enough about how our tank works to delete it I want to know there is still some kind of vent. Guess we could get a vented gas cap but is that a good way to go about it?

Here is a pic of mine. That black plastic line you see hanging there, with the 90° on the end, is the line that comes out of the fuel tank and used to go to the EVAP line (which now is my return line) and now that black plastic line is the new vent.
