FS20-20-D2 DUPLEX VALVES

Used to switch the fuel in an appliction where there is a fuel injected engine that needs flow return. It allows you to pipe surplus fuel to the same tank from which it was drawn. This avoids the worry of overfilling the return tank or having an overly complicated fuel system. Engines that can benefit from this valve are Surburu, Continental, Rotax, and Diesel engines. The FS20-20-D2 has two 3/8" sections where as the new FD25-20-D2 has one 1/2" feed section and on 3/8" return section. The valves can be supplied with either male or female fittings.
