DIAGRAM SHOWING FUEL SUPPLY CIRCUIT

1. Fuel supply manifold
2. Supply pipe from the tank to the filter
3. Filter
4. Supply pipe from filter to injectors
5. Return pipe
6. Breather pipe
7. Filler with ventilation and safety valve
8. Tank
9. Electric pump
10. Pressure regulator
11. Injectors

NOTE Given the special shape of the tank, when fuel is being introduced an air pocket tends to form in the lower part preventing it from being filled completely; the pipe (6) allows the air to flow from the bottom thereby enabling the tank to be filled completely.
