has a manual override handle which also serves as
a visual position indicator. A thermal relief valve
allows internal bypass of trapped fuel on outlet side
of shutoff valve, being set to open at 90 to 120 PSI
and to reseat at 80 PSI minimum. A check valve
manifold is connected to the inlet port of the fuel
