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.

You don't need a return line with that EFI fuel tank module. Just hook up the pressure line to your existing fuel line and then connect the fuel line to input at the Sniper. Cap off the return fitting on the Sniper.
