1984 K5 Long Overdue

[K5Pappi]

So here's what I'm working with.
My K5
I pulled the motor thinking it was a 305 and later realized it was a GM Goodwrench 350 crate motor
Old 350 vs New 400
(That's my 66 Nova SS I Plan on working on next year once the K5 is where I want it)
Planning on degreasing and pressure washing the engine bay, then sanding any rust I may find and painting the frame. going w/ a Holley Sniper 550-511K EFI kit
I rebuilt the 700R4 and transfer case a few years back when I first got the truck so we're all good there.
Once the engine swap is complete I'm going to pull all the carpet out and fix any floor pan issues I see and Rhyno Line the inside floor and bed. Going to swap out the tailgate for a truck tailgate as well.

Sweet looking rig I do like that color not red and not brown just right.

The name of the paint is dark cherry I guess... I got it in this color. I wish it were factory "Saddle Irid" 9960-66 color. Always been a fan of squares in that copper-brown color.

I have a fuel line question if you don't mind. When removing my mechanical fuel pump I noticed two lines returning to the fuel tank. reading a bit about it I see that Chevy incorporated this to prevent vapor lock. How do I identify which line is the supply & return or does it matter?

The supply will be the 3/8" line and the return will be smaller, either 5/16" or 1/4".
