Ummmmm NO. The EVAP takes fumes from the tank and purges them into the TB to burn them off. The EVAP system takes fumes from the tank and runs them thru the Charcoal Canister and as stated above purges them into the TB to be burned off in combustion. This keeps the tank from over pressurizing (even tho there is another purge/pressure valve mounted to the tank as well) and it's part of emissions. Typically what happens is you will throw an EVAP code as the charcoal canister fails and charcoal bits are pulled thru the Evap line and clog the solenoid throwing a code. You need to blow out the line and replace the canister and maybe the solenoid if you cannot get them out.

It doesn't hurt the car, you will just have a strong gas smell if it's not sealed off good as you will get the fumes from the tank into the engine bay. Lots of guys just leave it or remove the line from the charcoal canister that way it vents in the back of the car, but personally I say get it fixed and have the Evap system function the way it was designed. I think most people don't fix it as the canister is pretty expensive to replace.

Well everything is there I haven't touched it. Just where it enters the engine bay the hose is capped off. Can I just get a barbed fitting and a piece of hose to re-connect it to the evap solenoid, or do I have to replace the whole line? I don't (well didn't) have any codes or lights regarding the evap. Just a low oil light (sensor was broken and then capped off), and low coolant (sensor is garbage), that was it.
