Mounting the dosing pump, routing the fuel pipes
and mounting the fuel tank
The following safety instructions must be observed
when mounting the dosing pump, routing the fuel pipes
and mounting the fuel tank.

Failure to comply can result in malfunctions.
Danger!
Risk of fire, explosion, poisoning and injuries!
Caution when handling fuel.
• Switch off the vehicle engine and heater before
refuelling and before working on the fuel supply.
• No naked lights when handling fuel.
• Do not smoke.
• Do not inhale fuel vapours.
• Avoid any contact with the skin.
Caution!
Safety instructions for routing the fuel pipes!
• Only use a sharp knife to cut off fuel hoses and
pipes.
Interfaces must not be crushed and must be free
of burrs.
• The fuel pipe from the dosing pump to the heater
should be routed at a continuous rise.
• Fuel pipes must be fastened safely to avoid any
damage and / or noise production from vibrations
(recommended clearance of approx. 50 cm).
• Fuel pipes must be protected from any mechanical
damage.
• Route the fuel pipes so that any distortion of the
vehicle, engine movements etc. cannot have any
lasting effect on the service life.
• Parts carrying fuel must be protected from
interfering heat.
• Never route or fasten the fuel pipes to the heater or
vehicle exhaust system. At crossings, always ensure
adequate heat clearance, if necessary attach heat
deflection plates or protective hose (for Order No.
protective hose please refer to additional parts
catalogue).
• Dripping or evaporating fuel must never be allowed
to collect on hot parts or ignite on electric systems.
• When connecting fuel pipes with a fuel hose, always
mount the fuel pipes in a butt joint to prevent any
bubbles from forming.
Safety instructions for fuel pipes and fuel tanks
in buses and coaches
• In buses and coaches, fuel pipes and fuel tanks
must not be routed through the passenger
compartment or driver’s cab.
• Fuel tanks in buses and coaches must be
positioned in such a way that the exits are not in
direct danger from a possible fire.
• Comply with the regulations and safety instructions
for this chapter on page 4 – 7.
• For noise reasons, do not rigidly fit fuel pipes onto
structural sound transferring components.
A sponge rubber hose can be pushed over the fuel
tubes for nose reduction.
