Fuel lines/Pump & Tank Questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hello,
I have a 1972 C/10 1/2 ton 2wd with 350 and TH350.
Trying to figure out if fuel system is hooked up properly with what's currently there. I have a fuel pump with inlet from tank, outlet to carb, and another smaller outlet, which I assume is a return of sorts. I currently have a Evaporative Emission Control gas tank, but none of the canister related items were there. So if I hook up the smaller line back to the tank as a return will that be ok? I have pasted a pictures of tank/pump like I have, that is if I inserted them right.

Thanks in advance for any help guidance
