312000119 - 1040A FUEL TANK AND COMPONENTS
SUBMERGED PUMP ASSEMBLY COMPLETE WITH LEVEL GAUGE
The fuel pump is part of a single assembly with the level gauge and fuel filter. Components cannot therefore be replaced individually.

| 3/4 | B | 76 ± 3 | 165 | 156,6 ± 2 |
| 1/2 | C | 134 ± 3 | 125 | 116,9 ± 2 |
| 1/4 | D | 206 ± 3 | 75 | 67,1 ± 2 |
| R | E | 235 ± 3 | 55 | 47,2 ± 2 |
| 0 | F | 299 + 3,5 / -3,3 | 10,5 | 3 ± 2 |
FUEL PUMP
The fuel pump is equipped with a permanent magnet electric motor (1) that controls the pump (2) and a terminal mount cover (3) that contains the electrical and hydraulic connections.The pump stage is single, peripheral flow type with high performance under low voltage and temperature conditions.The advantages compared to pumps that operate on volumetric principles are as follows:
- reduced weight;
- limited size.
Pump working point
The pump specifications are described below:
- Capacity: = 135 l/h
- Pressure: 2.6 bar
- Supply current: 12.5V
- Valve control pressure: between 5 bar and 8.5 bar
