Diesel Fuel Pumps

Fuel pumps are remanufactured in a climate-controlled, electronically filtered environment. As a Service Dealer for both Bosch and Stanadyne, JASPER’s Diesel Air and Fuel Component Division employs Associates that have been trained in original equipment specifications and processes.

JASPER® also focuses on processes that are specific to pump manufacturer, design and application. For example:

High-pressure Oil Pumps for 6.0L, 444, 466E and 3126 applications:

• Custom sized O-rings installed to prevent leaks from the rear end sealing plate
• 100% of the O-rings within the pump are replaced, along with all discharge fittings
• Installation of a set screw through the housing stops the swash plate from turning and   prevents pressure and flow loss
• The rotor thrust washer, a key wear item, is replaced and lapped to match the rotor in order to prevent cross leakage
• 6.0L and 466E pumps receive a new bolt and friction washer on the drive gear
• Testing with inspections for pressure, flow and leaks using a custom built test stand and software

Stanadyne DS pump for GM 6.5TE engines

• 100% NEW PMD
• 100% NEW transfer pump blades
• 100% NEW low-drag armature

Stanadyne DB2 pump for GM 6.2 & 6.5 and International 6.9 & 7.3 engines

• 100% NEW transfer pump blades
• 100% NEW delivery valve
• 100% NEW advanced piston

Every fuel injection pump is thoroughly tested and precisely calibrated with computer-aided test equipment for consistent quality and performance. All Bosch injection pumps are calibrated on a state of the art Bosch 815 calibration stand. HEUI high pressure oil pumps are tested on a custom-built test stand to provide a live simulation of in-the-vehicle operation.

JASPER remanufactured fuel pumps are covered by a One Year Parts & Labor Warranty with no mileage restrictions. A full warranty disclosure is available on this website.
