I asked this two years ago

General opinion is that it isn't needed.

Isn't that the incoming fuel line?

The ends can be capped, though most people leave some kind of a schrader valve on , so you can attached a fuel gauge. You will need a cross over line to feed both banks.

i ahve teh cross over and it will be at teh back. i have one line coming into teh drivers rail with a fitting so i can attach a gage. and that is just before the elbow on teh drivers side line. do i turn the outlet ofteh passenger side rail into a return line to connect to the other line that is left (evap line). or is it not needed at all?

ok so i answered my last question as far as i know. and this is the thread that i found pertaoning to it. and it says that i do not need teh evap line to be hooked up but it will just leave a gas smell is all in a garage. so no biggie. but any one can correct me if i am wrong. https://ls1tech.com/forums/showthrea...ap+line+needed so teh summary is no the pu;se damper is not needed neither is teh line that comes off of it. but also please refer to the thread above for any questions. i will hopefuly have pics for any one this week just to show everything off.
