Since 1981, Spencer Diesel has been a premier rebuilder of diesel injection pumps, turbochargers, and injectors. Our skilled technicians are factory-authorized to assist with troubleshooting and service. We can repair or provide rebuilt exchange units for immediate delivery on most fuel injection pump applications. Backing up our technicians is an extensive inventory. We have over 1000 pumps ready for shipment along with turbos and nozzles. We use the manufacturer's mandatory tools in completing our repairs. Our calibration room is equipped with 17 test stands so technicians can move the repair process through in a timely manner. Since our inception, we have continued to build on our reputation as a trusted provider of the parts we sell.
