[0032] A fuel pump 3, which is mounted on a pump body mounting base 5;

[0033] A support frame 2, which is movably connected to the side of the pump body mounting seat 5;

[0034] Flange 1, which is located above the support frame 2 and is connected and fixed to the support frame 2 via a support rod 21;

[0035] The fuel pump 3 is connected with a fuel injection pipeline and a fuel outlet pipeline. The fuel outlet pipeline is connected with the flange 1. The fuel injection pipeline is arranged on a pump body support seat.

[0036] Furthermore, the pump body support seat is provided with an arc-shaped sliding guide groove 52, and the side surface of the sliding guide groove 52 has an inserting groove 24 in the vertical direction.

After the support frame 2 slides along the sliding guide groove 52 through the guide column 26, it can be restored to the initial position by the elastic force of the spring 23, and the limit nuts 27 and gaskets at both ends of the guide column 26 are used to prevent the guide column 26 from being separated from the sliding guide groove 52 and the support frame 2.

[0038] Furthermore, one side of the plug slot 24 has a limiting plate 25 for limiting the position.

[0039] Furthermore, the fuel pump 3 is externally mounted with a fuel pump fixing bracket 306, and the fuel pump fixing bracket 306 is fixedly engaged with the pump body mounting seat 5. The fuel pump 3 is fixed to the pump body mounting seat 5 via the fuel pump fixing bracket 306.
