FUEL SYSTEM
The Proheat Air heater comes complete with all fuel system components
required to supply the heater with diesel fuel. Do not substitute any hardware
or tap in to the OEM fuel lines.
General Considerations
• Cut fuel line with a sharp knife on a solid surface and ensure all cuts are
square with no burrs or pinching (refer to figure 18).
• Mount the fuel pump in a vertical position and within 27.5” (700 mm) of
the fuel pickup using the supplied mounting hardware (refer to figure 17).
• Route fuel lines away from any abrasive corners and hot or moving parts
and ensure they are well secured.
• Protect any exposed fuel line and fuel pump wires with wire loom.
