The evaporative l
oss flange assembly is fitted to the top of the tank via a seal and locking ring. The assembly is removeable
complete with the fitted components.
The vapour vent / rollover valve is a push fit via a sealing grommet. The fuel pump connector is push fitted and crimped
into a location tube on the underside of the flange.

The fuel fil
ler cap is the same as
that used on non-ORVR systems.
The check valve assembly is a push fit into the end of the fuel filler tube and is accessible with the evaporative flange
removed. The valve has a light spring load ing and opens under the inflow of fuel.
ORVR Evaporative Loss Flange Assembly

The evaporative loss flange assembly is fitted to the top of the tank via a seal and locking ring arrangement identical to that
used for non-ORVR systems. The assembly is re moveable complete with the fitted components.
The fuel level vent valve (FLVV) is mounted in the ELF assembly via a bayonet fitting : it is turned approximately 90 °
clockwise to release. The grade vent valve and pressure sensor are push in fits via sealing gromme ts : note that, due to the
tight fit, removal of these components may require cutting the grommets. The fuel pump connector is push fitted and
crimped into a location tube on the underside of the flange.
