Fuel cell fittings -08 to Fuel lines?

I got a 12 gal cell with suply and return sump fittings coming out -08 I need to come off those to a barb for the rubber fuel injection lines, the suply needs to go from -08 to 3/8" barb(to the pump)and the return from -08 to 5/16" barb(return line)I also need to come off the vent which is -06 to 5/16" barb

-08 is 1/2", so you would need a female -08 to male -06 adapter, or i believe you can replace the bulkhead AN fittings in the cell to -06 AN, which is 3/8". I am running 3/8 on my supply and return.
