Installing the Fuel Pump and Fuel Lines
NOTE: Do not connect unit fuel lines into any truck/trailer fuel lines.
1. The fuel pump must be installed as close to the fuel tank as possible
and not more than 762 mm (30.00 in.) above the fuel in the fuel tank.
2. Fuel lines should be routed in a protective housing with no kinks or
sharp bends.
3. Rubber grommets must be used when routing fuel lines through sheet
metal.
4. Secure all fuel lines with provided clamps.
5. Remove the protective plugs from each of the fuel pick up tubes on the
fuel tank and install fuel line fittings.
6. From the unit, route and install the fuel supply line to the upper fuel
line fitting on the fuel pump. Tighten the fuel line fittings securely.
7. From the fuel pump, route the lower fuel supply line to the fuel tank.
• Cut the end of the nylon fuel supply line at a 45 degree angle and
insert into one of the fuel line fittings.
• Feed the fuel line down into the tank until it hits bottom, then pull it
back up 25 mm (1.00 in.) and tighten the fuel line fitting securely.
8. From the unit, route the fuel return line to the fuel tank.
• Insert the fuel return line into the other fuel line fitting and tighten
the fuel line fitting securely.
9. Remove the plastic cap from the fuel vent and point the outlet towards
the rear of the truck.
IMPORTANT: The factory installed fuel tank air vent must be in place
and functional for the Thermo King unit’s fuel system to operate
correctly and for the fuel tank to remain in compliance with Federal
Motor Carrier Safety Administration specifications (title 49, paragraph
393.67). A plugged or restricted fuel tank air vent can result in premature
damage to the fuel pump and could also cause severe damage to the fuel
tank. NEVER remove or install any other component in place of the fuel
tank air vent.
10. Operate the unit and check all fuel line fittings for fuel leaks.
DANGER: The Thermo King fuel pump should be installed onto
the supplied mounting bracket. The fuel pump and fuel lines
should be installed a safe distance away from the extreme heat
generated by the Diesel Particulate Filter (DPF) or exhaust system
components on the truck. Failure to do so could result in damage
to equipment or fire!
DANGER: Leaking fuel lines could cause a fire resulting in death
or serious injury All fuel lines must be tight and leak free!
DANGER: Do not route fuel lines with battery cables or electrical
wires, as this could cause a fire!
