Have a Backdraft with aluminum tank. There is a -06 an bulkhead fitting that is currently capped almost at top(vertical part of tank)facing towards the front of car. Can/should I use this to place a fuel vent valve? Rollover valve? My return line is tee’d into the filler tube.

I have a g-surge high pressure pump in the engine compartment. It requires a full return line to the tank. Still using low psi pump at tank in conjunction with this high psi pump. Also, have a Fitech EFI TB.

When my racing cap is closed it is tight, meaning it is not allowing any air into the fuel tank/system. Won’t this cause a vacuum in the system?

Not sure if my tank needs to be vented or not and if this bulkhead fitting should be used as a place for returning fuel or venting.
