Fuel Return Line?

Hey Everyone,

First post here in several years since my 84 Sierra was totaled. I picked up a super clean 1986 Burb that is in near perfect original condition. Nothing has been modified, until now

I bought a Holley Sniper EFI system from Summit today and it should be here tomorrow. I have to have a return line to the tank and see there are a couple of lines on the sending unit. Does anyone know if one of those lines run from the tank to the engine bay (other than the supply line)?

I'd like to use an existing line if it is up to the quality I need for fuel return under pressure. Or at the very least, plug in to an open port on my sending unit so I don't have to drill in to a brand new fuel tank.

I have done so much, for so long, with so little, I can do anything with nothing!
