im going to be hooking up my fuel cell today. I bought the 12gal one made by summit racing. -6an on the top which is effectively in the compartment, and two -8an outlets in the sump. now for the fuel return line am i supposed to use the -6 that is on the top of the cell? Or am i supposed to use the -6 as a vent and somehow expect the fuel to push through back into the tank via the -8an on the sump?

 

The -6 is the vent fitting, so you will need to use one of the spare bottom fittings as the return (remember it is pressurized) or add another bulkhead connector to the top.
