Flange Assembly
The flange assembly (Figure 83) is designed for 20,685 kPa (3,000 psi) service pressure and is the refueling connection to fill the vehicle. The
assembly is mounted behind the fuel filler door and attached to the fuel filler housing, similar to a gasoline vehicle. This assembly consists of
an NGVP1 type receptacle with a 150 micron filter (which can be serviced), a spring loaded check valve to allow filling of the vehicle and a
manually opened bypass to provide safe venting of the fuel system. The vehicle is refueled by attaching the fuel station fill nozzle to the
receptacle and locking into place.
