VP44 1 Year

Thoroughbred Diesel offers replacement Bosch Vp44 Fuel Injection Pumps that have been rebuilt by certified Bosch tech and have been tested on a test stand for 4hrs before the pump is sent to you. Bosch VP 44 diesel pumps are also upgraded with all the latest upgrades required by Bosch. Our VP44 injection pumps come with a 1yr unlimited mileage warranty. If you are placing performance parts on your truck it is highly recommended that you use a performance lift pump such as the Airdog fuel system or Fass Fuel Systems. An Airdog or Fass Fuel System will supply the Injection pump with the fuel pressure that is need no matter what performance upgrades you have on your truck. We also offer several different gauge options from Autometer and Isspro to monitor your fuel pressure so you know when your lift pump is going out and can fix the problem before you lose your Injection Pump. The cheapest way to monitor your fuel pressure would be BD's early warning light. Preventing problems before they occur is the best way to take care of your truck.

Original Airdog

The AirDog Fuel Preporator, with the capability to provide fuel at flows and pressures beyond the maximum requirements of the engine, receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of moisture. The fuel passes through the water separator which removes the water and large particulate contaminates that could damage or jam the gearator fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining, enters the fuel pump.

The fuel, now under positive pressure flow, enters the filter. As the fuel passes through the filter media and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated. Through the positive fuel air separation features of the patented Fuel Preporator the separated air/vapor is discharged from the filter through the Primary Air/Vapor Discharge Port and into the return to tank passage after the regulator. The fuel passing through the filter media (free of contaminates & power robbing air/vapor and at pressures and flows to meet the needs of the engine exits the fuel filter through two passageways. The fuel for the engine, passes into the fuel pickup tube and out to the engine).

The excess fuel not needed by the engine is released through the pressure regulator to combine with the air/vapor and foam as it returns to the fuel tank. The regulator controls the fuel pressure to the engine.
