It is provided between 0.36 and adjacent screw thread under projection cooperation, when the corrugated tube is subject to oil pressure to extrude in use, ripple
Pipe occurs that phenomenon of rupture occurs, and bulk strength is poor, reduces the service life of corrugated tube, total so as to also reduce fuel pump
Into service life；Caliber such as ripple inside pipe wall one end is less than 0.36 and adjacent with the caliber ratio of the ripple inside pipe wall other end
Screw thread between be provided with projection coordinate under, the corrugated tube in use be subject to oil pressure extrude when, corrugated tube occurs deformation
Phenomenon occurs, and bulk strength is poor, reduces the service life of corrugated tube, so as to also reduce the use longevity of fuel oil pump assembly
Life；So the caliber of the ripple inside pipe wall one end be 0.36 with the caliber ratio of the ripple inside pipe wall other end and adjacent screw thread it
Between be provided with projection coordinate under it is relatively reasonable, corrugated tube bulk strength is stronger, finally extends the service life of fuel oil pump assembly.
This utility model is further arranged to：Also include being arranged at the drainage screen of bellows interior.
By adopting above-mentioned technical proposal, the effect of filtration is served, it is to avoid the debris in fuel oil enter into car engine
Electromotor is caused to be damaged in machine.
