Removal and Installation of
N-2007 LP Regulator
Follow the procedures below for removal and
reinstallation of the N-2007 regulator in certified
systems.
N-2007 Removal Steps
Refer to Figure 28.
1. Close the liquid outlet valve in the forklift cylinder
or fuel storage container.
2. Purge the system of fuel by starting the engine
and running until all trapped fuel in the system is
exhausted and the engine shuts down.
3. Key switch in “OFF” position.
4. Remove the fuel inlet line (1) from the lock-off, the
two vacuum lines (2) from the branch-tee fitting in
the regulator vent and disconnect the lock-off
connector (3).
5. Remove the four rear-mounting bolts that hold the
regulator to the support bracket. This will allow
easier access to the remaining hose clamps.
6. Remove the two cooling lines (4) from the
regulator. NOTE: Either drain the coolant system
or clamp off the coolant lines as close to the
regulator as possible to avoid a coolant spill when
these lines are disconnected.
7. Remove the fuel vapor outlet hose (5) from the
regulator.
8. Remove the nipple extension (6) with the lock-off
from the regulator.
