VERY noob questions - I'm fairly new to LS1's so I want to make sure. Please bear with me!

Engine is being pieced together and I plan on using the C5 Corvette FPR/Filter combo in an import.

[LEFT PICTURE] This line, the one with a green-capped schrader valve up towards the TB, is it a return line, or some sort of vapor line? Or what? What is the simplest (but safe) thing to do with it? This car will not need to pass emissions.

[RIGHT PICTURE] The line going into the drivers side fuel rail is the fuel supply inlet? I can plumb straight into this from the C5 filter, correct?

Thanks so much you guys!

The left is the evap silinoid, it suckes the fumes out of the gas tank. If u unhook it your car will smeel like gas at every light. the right is your fuel pressure line

So where should I route the evap so I don't have a fume problem?

Or what exactly should I do with it?

Thanks for the response.

It hooks to the intake vacuum behind the TB.

If you are not venting your tank to it than it can be removed and plug the vacuum line out of the intake.

devilssled and Nate, thanks for the help.

So if I take the evap line out of the IM and plug it, will I get the fume problem that I've seen mentioned or will it have any (other) adverse consequences?
