The bolts pass through the connecting holes and the threaded holes to tightly connect the mounting flange 51 and the oil suction port flange 61 together, so that the booster pump 6 is stably mounted on the mounting bracket 5.

[0033] The booster pump 6 and the bottom plate of the mounting bracket 5 have a gap, and a plurality of through holes 52 are arranged on the bottom plate, which facilitates the flow of fuel and heat dissipation.

[0034] The mounting direction of the booster pump 6 can be set according to the test requirements. For example, as shown in Figure 2 , the central axis of the booster pump 6 is parallel to the width direction of the fuel tank.
