I have a 2015 Hyundai Accent with 45,000kms. The tank fuel pump has failed twice and the high pressure fuel pump once. Anyone know what would cause such failures?

  • High pressure pumps usually fail due to lack of maintenance, the spring usually ends up breaking or the diaphragm starts to leak. – Ben Aug 1 '18 at 20:31
  • How certain are you that it's the fuel pump that's failing, have you checked for shorts, is the pump pumping fuel when power is applied to the 2 terminals that have continuity – user38183 Dec 30 '18 at 12:15

Could well be poor ie cheap fuel - cheap fuel can be cheap because while it meets the minimum standards it can be light on some of the additives.

Another possibility is a cheap fuel filter but as it is relatively new perhaps not.
