Fig. 2 is the connection diagram of the utility model pressure regulator valve and oil storage barrel；
Fig. 3 is the connection diagram of the utility model metal guide rod and fine filter.
Embodiment
Below in conjunction with attached drawing, the utility model is illustrated.
Referring to Fig. 1, a kind of electric fuel pump assembly, including：Protective cap 1, flange 2, pressure regulator valve 3, pressure regulator valve clip 4,
Sensor group founds 5, two metal guide rods 6, electric fuel punp 7, oil storage barrel 8, preliminary filter 9, fine filter 10, harness 11 and spring
12；Oil outlet 21 and bellows 22 are provided with the flange 2, described 2, two metal guide rods 6 of flange and fine filter 10 are successively
Connection；The electric fuel punp 7 is connected with the bellows 22 and the fine filter 10 respectively, and during work, electric fuel punp 7 opens
It is dynamic, fuel oil is sucked from fine filter 10, electric fuel punp 7 is then extruded, by bellows 22 and oil outlet 21, transports to automobile
Engine.
It is connected in addition, the sensor group stands 5 with the fine filter 10, as shown in Figure 1, sensor group stands 5 and fine filter
