What does a diesel injection pump rebuild cost?

An injection pump rebuild is priced three ways: a bench test and report, a rebuild of your own pump, or an exchange unit from stock with a core charge refunded when your pump arrives. Diesel Fuel Injection Service in Scappoose, Oregon has rebuilt and tested pumps since 2006 and ships exchange units nationwide. Call (503) 235-1947 with the pump part number and we quote all three.

What decides the number

  • Pump family: rotary (VE, VP44, DB2, DS4), inline (P7100, P-pump), common rail (CP3, CP4, Denso HP3/HP4) and HEUI each have different parts and test time
  • Condition: a pump run dry or with fuel contamination needs a housing, head and rotor or plungers, not just seals
  • Calibration: every rebuilt pump is run on the test bench to the maker's spec sheet before it ships
  • Core: exchange pricing assumes a rebuildable core; cracked housings and seized units are charged extra

Rebuild, exchange or new?

  • Rebuild your own when it is a rare or matched pump, or the truck is down and you can wait for the bench
  • Exchange when the truck needs to be back today — we stock the common Cummins, Duramax, Power Stroke and ag/industrial pumps
  • New only when a reman is not made for your pump or the maker has superseded it

Questions

Most common pumps are on and off the bench in 2–5 business days once parts are in; exchange units ship the same or next day.

Yes — a bench test tells us whether the pump needs seals, a calibration or a full rebuild, and you get the report either way.

A deposit on the exchange unit, refunded when your rebuildable core arrives; see our core charge page.

Yes, nationwide, from Scappoose, Oregon.
