Evap line on obs

Haven't seen any threads where this is addressed. My 96 tahoe has a hard plastic line from The fuel tank to right below the driver side battery tray. I put a vacuum cap on it for now but I'm concerned if this will be enough. Anyone done anything about this?

Think I just deleted it and put a cap on it, would like to know if it's bad this way or not

LOL I'm probably going to get a barbed fitting and just drill and tap the intake tube and run fuel hose from the evaporate line

my problem is the CAI i pieced together i have the air filter going straight to the MAF & the the tube. i will have to put the line after the MAF.
if it doesn't work then i'll reconfigure.

I wonder what the difference would be putting it before or after the maf

after looking at the old parts mine went into the canister but didn't go anywhere after that. my canister has i little breather looking cap on it.
maybe i'll just leave the canister for now.

I deleted all of that (canister and line running to tank) and have about a 10" hose from my tank that sits inside the rear frame rail to help the tank breathe

That is pretty much what I did also. My only issue with this is, when I have the truck in a closed garage, it smells the garage up something terrible. Guess thats what the charcoal cannister helped with.

I kept the charcoal cannister in mine and plumbed it into the intake.

In retrospect, thats what I should have done as well. Its gone now, lol. The cannister/gas tank tube system is the tanks only means of venting, correct? Just wondering what the older 80's/90's GM pickups had for a gas tank vent system?
