Pump components

The internal parts that decide whether a rebuilt pump holds pressure for a year or for a week. Ground in-house, matched in pairs, supplied per piece or as a complete overhaul kit.

Precision internals

Ground in-house, matched in pairs

A plunger and its barrel are ground together until the clearance is 0.5–1 µm. Swap one of them and the pump delivers fuel like a 40,000-hour worn unit. That is why we never sell them from random bins.

  • Plunger-to-barrel clearance verified individually, marked with its pair number
  • Delivery valves tested for seating vacuum and opening pressure
  • Head rotors for VE pumps supplied complete with distributor and valve
  • SCV valves flow-tested before packing
