INJECTION FEED SYSTEM BY MECHANICAL ROTARY PUMP
General information
Fuel feed system is composed by:
- Fuel tank (placed on the machine)
- Fuel delivery and back−flow to tank
- Fuel pre−filter (if available, it is usually placed close to the engine on th e machine fr ame)
- Priming pump, assembled to the engine and dr iven by the camshaft
