I’m looking at going with the Holley Sniper efi kit. Everything seems pretty easy and straight forward except how and where to run a return line. It appears that there is a vapor/breather line that runs from the tank up to the engine bay. Can you use this as a return and then use a vented cap? Or do I need to drop the tank, drain the fuel, then drill a hole to install a fitting?
