The utility model discloses an automobile
fuel pump with a good plugging effect, which comprises a pump body, an oil inlet
pipe is connected to the outer side of the pump body, an oil outlet
pipe is connected to the outer side of the pump body, and connecting mechanisms are arranged on the oil inlet
pipe and the oil outlet pipe. The connecting mechanism comprises a clamping sleeve, an external pipe, sliding holes, clamping blocks, clamping grooves, a sealing strip, a sealing
gasket and a pressing mechanism, the clamping sleeve is fixed to the top ends of the oil inlet pipe and the oil outlet pipe, the external pipe is inserted into the clamping sleeve, the multiple sets of sliding holes are distributed in the outer wall of the clamping sleeve, and the multiple sets of clamping blocks slide in the multiple sets of sliding holes correspondingly; the multiple sets of clamping grooves are distributed in the outer wall of the outer connecting pipe and clamped with the multiple sets of clamping blocks respectively, the multiple sets of sealing strips are distributed on the outer wall of the outer connecting pipe to form a first sealing barrier, the sealing
gasket on the inner side tightly abuts against the outer connecting pipe to form a second sealing barrier, and the sealing performance of the connecting position is remarkably improved through the double-sealing structure.
