P30 V8-6.5L DSL Turbo (1999)
Fuel Heater
The fuel heater operates when the temperature of fuel at the inlet of the filter housing is cold enough to possibly cause waxing that could restrict the flow
to the injection pump. A control circuit inside of the fuel heater completes the circuit for the heater element when the fuel heater senses a temperature
below 8°C (46°F).
Rubber Fuel Hoses
The fuel feed and return pipes and hoses extend from the fuel sender to the fuel manager/filter. They are secured with clamps and are routed along the
frame side member.
Some fuel feed pipes have threaded connections that are sealed with replaceable O-ring seals. These O-ring seals are made of special material, and
should only be serviced with the correct service part.
