A Series Diesel Engine Fuel System 78
High Pressure Fuel Line
Caution : The high pressure lines must be clamped
securely and routed so they do not contact
each other or any other component.
The high pressure fuel lines are designed and
manufactured to deliver fuel at injection pressure to
the injectors. The high pressure pulses will cause the
lines to expand and contract during the injection
cycle.
Caution : Do not weld or substitute lines; use only
the specified part number for the engine.
The length, internal size and rigidity of the lines is
critical to smooth engine operation.
