SP 32. Bleeding Fuel System
High-pressure fluid remaining in fuel lines can cause
serious injury. Do not disconnect or attempt repair of fuel
lines, sensors, or any other components between the
high pressure fuel pump and nozzles on engines with
High Pressure Common Rail (HPCR) fuel system. Only
technicians familiar with this type of system can perfo
repairs. (See your Northern Lights dealer.)
Escaping fluid under pressure can penetrate the skin
causing serious injury. Avoid hazards by relieving
pressure before connecting hydraulic or other lines.
Tighten all connections before applying pressure. Search
for leaks with a piece of cardboard. Protect hands and
body from high pressure fluids.
If an accident occurs, see a doctor immediately. Any fluid
injected into the skin must be surgically removed within a
few hours or gangrene may result.
IMPORTANT:
Four-valve cylinder head engines are
especially sensitive to fuel contamination. Do
not crack any fuel lines to bleed the fuel system.
NOTE: Normally the fuel system on these engines is
self-priming and self-bleeding, and does not require
a bleeding procedure by the operator.
If engine will not start after filter changes, turn ignition
keyON for 60 seconds to prime the fuel system. It may be
necessary to turn the key off and on again to re-prime the
system.
