e:: Some OEM’s offer a fuel tank option which provides three auxiliary fuel fitting connections. With this option, the
fuel pickup tube and adapter plate are not needed. Simply route and connect the APU’s fuel supply and return
lines and the heater’s fuel supply line to these fittings. Always check your fuel tank for these fittings before
installing the fuel pickup tube or adapter plate.
