Sniper EFI Return on Stock Tank With Drop in Fuel Pump; How?

Hello all,
I’m running Sniper EFI on my 360 and was wondering how I’m to run the return. I’m using a stock tank with one of these drop in fuel pump modules:
Holley 12-319 Holley OEM Style EFI Fuel Tank Modules | Summit Racing
I bought my EFI kit slightly used and it didn’t come with the return line kit.

I don't know, did you start by reading the destructions? Does it need a separate regulator? What year / model car do you have? "You just might" have to figure out how to rework the tank or maybe the filler tube for a return port. Be damn sure you do research so you don't end up with a non-vented tank situation
