Note:
Excessive fuel lift pump pressure may damage
the fuel filter element and/or leakage may occur
along seals.
A primer pump (2) is fitted for bleeding the fuel
system. To operate the primer pump (2), it must
first be loosened.
On the upward stroke, the volume above the
priming pump piston is reduced. This causes the
non-return valve (6) to close and the fuel flows
along the piston seal to the bottom of the piston.
On the downward stroke, the volume below the
priming pump piston is reduced. This forces the
fuel via the fuel lift pump section to the fuel fine
filter.
At the bottom of the fuel lift pump is a pressure-
relief area (10).
The pressure-relief area prevents fuel
penetrating the lubrication system through
sealing ring C and lubricating oil penetrating the
fuel system through sealing ring D in the event of
leakage.
A visual inspection for leaks is also possible
with this.
