2002 LQ4 swap, gas tank/fuel system questions. Please help
I am swapping a 2002 LQ4 into my 85 SWB. My Fuel system consists of an 87 TBI tank and sending unit, EP381 pump, Wix Corvette filter/regulator. I have already built and installed the feed and return from the tank to the filter. I need to know what to do with the 3rd line that is in the middle. Can I block it off completely or does it have to go somewhere? Emissions is not a concern at the present time.

The big one, the 3/4 inch one goes to the filler neck, the 3/8 is the feed, the 5/16 is the return and the 1/4 goes to the charcoal canister. Which one are you confused about?

The smaller one on the sending unit, I should have clarified that. I don't have the charcoal canister anymore.
