So I finalized the fuel configuration for the RCRP4. This is a dual tank (one in each "sponson", and will be feeding a hungry LS7 with fuel injection. I have -10 AN fittings for the supply side at the bottom back of tanks, -6 AN fittings 5" above the supply for the return lines. I am connecting a 100 micron fuel filter (SS Mesh) before a Aeromotive A1000 pump then a 10 micron filter after the pump with a checkvalve. This will connect from each bank and meet between the rails at a regulator that will feed back to either tank via manual selector. Pumps will be run individually and electrically from the cockpit. I will see if I can setup a cable operated tank selector rather than run the fuel into the cockpit. I confirmed this setup with Aeromotive, and I just need to get the check valves as I bought the rest of this stuff (and it is $$$) already.
