Fuel system
Circuit description
The fuel system is based on a fuel feed pump
and an in-line mechanical injection pump.
The dimension "a" will be the maximum possible. Mount the inlet and return as far apart as
possible. Distance "a"> 300 mm. Do not exceed height "h". "H"
≤
1500 mm.
Fuel specifications
Use ASTM diesel fuel No.2-D for the best engine performance, to prevent engine damage.
Never use kerosene, heavy diesel fuel or biodiesel. It is essential to use clean and filtered diesel oil.
The use of diesel oil that does not comply with the technical specifications may affect warranty
coverage and cause serious damage in the injection system and internal engine components.
Maintenance task. Fuel level inspection
Periodically, it is necessary to check the fuel level to assure the operation of the engine. On
top of that, if fuel pump sucks air when the fuel level is lower than pump suction, it could break.
Whenever possible, keep the fuel tank full. The temperature changes may cause
condensation of the damp air present in the tank and this water accumulates at the bottom. It can
cause an increase of corrosion or an impossibility of starting the engine if this water is aspired by the
fuel pump.
Maintenance task. Fuel tank clean
The fuel impurities could obstruct the suction pump. For this reason, drain out the content of
the fuel tank to remove condensate and any foreign material. Then, wash the tank with fuel and refill
it.
