I'm waiting for the new FiTech 2 bbl system designed for between 150 and 400 hp applications, perfect for our slants! They should be available at the end of March. I will be running this on an M1 2 bbl intake with Dutra Duals with upgraded ignition. FiTech's Fuel supply kit (#4005) does recommend a 3/8" diameter pickup in the tank and they supply a return line as well NOT to be tied into the vent line. Should be a nice reliable system.
