A worn or damaged internal transfer pump, plunger, or fueling valve can affect the pressure and amount of fuel injected, thus reducing the power from the engine. Generally, if the fuel injection pump is injecting fuel from one outlet, it will deliver from all outlets. VP44 Timing Principles Timing in the VP44 is controlled by an internal timing piston coupled to a cam ring inside the pump. The timing piston is moved by fuel pressure. The amount of fuel pressure in the timing piston assembly housing is controlled by an internal transfer pump and a pulsating timing solenoid valve. As pump speed increases, the fuel pressure to the timing piston assembly also increases. Based on the inputs from the fuel pump control module (FPCM), the timing solenoid valve pulses to vary the pressure to move the timing piston, which results in the cam ring moving to the desired position to achieve the commanded timing. The more pressure created by the internal transfer pump and timing solenoid valve, the more the timing will advance; therefore, timing range capability is increased at higher rpm's.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003e*Performance chip \u0026amp; add on disclaimer\u003c\/strong\u003e\u003cspan\u003e - Tampering with the pumps wires can cause premature pump failure. If the wires are cut the pump is no longer warrantable, and any repairs that need to be made to the injection pump will be the buyers responsibility. In the VP44 pump the fuel is used to cool and lubricate the pump, and the tolerances between the head and the rotor is very fine. Performance chip add on's affect the cooling rate of the pump. The pump will become hotter due to excessive RPM's from the chips programming. When the throttle is backed off the fuel to the pump is reduced, and the pumps cooling capabilities are greatly reduced. Since the pump is hotter from the increased RPM's the rotor seizes in the head and the pump fails. An alternative to cutting into the pumps wires is to use a chip that plugs directly into the trucks ECM. This approach will allow for an increase in HP while not excessively heating the fuel pump.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e*IMAGE IS GENERIC, ACTUAL PRODUCT WILL DIFFER. \u003c\/span\u003e\u003c\/p\u003e","brand":"Thoroughbred Diesel","offers":[{"title":"Default Title","offer_id":44303073968378,"sku":"17XVP442YR","price":1595.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/9304\/7546\/files\/51_e4kEu26S._AC_SY300_SX300_aebaac17-8f3e-462e-b670-ba77ef36dc8a.jpg?v=1734385173"},{"product_id":"thoroughbred-diesel-15xvp442yr-8010","title":"VP44 Injector Pump (24 Month Warranty) - 98.5-02 Cummins Auto\/5 speed Manual\/98.5-99 6 speed Non HO - 15XVP442YR","description":"\u003cp\u003eModel 15XVP442YR\u003c\/p\u003e\n\u003cp\u003eWe pride ourselves in offering the best quality VP44 with the longest warranty in the industry!

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.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eThe fuel injection pump (VP44) is an electronic rotary distributor pump.

A worn or damaged internal transfer pump, plunger, or fueling valve can affect the pressure and amount of fuel injected, thus reducing the power from the engine. Generally, if the fuel injection pump is injecting fuel from one outlet, it will deliver from all outlets. VP44 Timing Principles Timing in the VP44 is controlled by an internal timing piston coupled to a cam ring inside the pump. The timing piston is moved by fuel pressure. The amount of fuel pressure in the timing piston assembly housing is controlled by an internal transfer pump and a pulsating timing solenoid valve. As pump speed increases, the fuel pressure to the timing piston assembly also increases. Based on the inputs from the fuel pump control module (FPCM), the timing solenoid valve pulses to vary the pressure to move the timing piston, which results in the cam ring moving to the desired position to achieve the commanded timing. The more pressure created by the internal transfer pump and timing solenoid valve, the more the timing will advance; therefore, timing range capability is increased at higher rpm's.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003e*Performance chip \u0026amp; add on disclaimer\u003c\/strong\u003e\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e- Tampering with the pumps wires can cause premature pump failure. If the wires are cut the pump is no longer warrantable, and any repairs that need to be made to the injection pump will be the buyers responsibility. In the VP44 pump the fuel is used to cool and lubricate the pump, and the tolerances between the head and the rotor is very fine. Performance chip add on's affect the cooling rate of the pump. The pump will become hotter due to excessive RPM's from the chips programming. When the throttle is backed off the fuel to the pump is reduced, and the pumps cooling capabilities are greatly reduced. Since the pump is hotter from the increased RPM's the rotor seizes in the head and the pump fails. An alternative to cutting into the pumps wires is to use a chip that plugs directly into the trucks ECM. This approach will allow for an increase in HP while not excessively heating the fuel pump.\u003c\/p\u003e","brand":"Thoroughbred Diesel","offers":[{"title":"Default Title","offer_id":44303095693562,"sku":"17XVP441YR","price":1125.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/9304\/7546\/files\/51_e4kEu26S._AC_SY300_SX300_00d76133-e649-4740-b75e-eb645a8dedbf.jpg?v=1734105137"}],"url":"https:\/\/www.powerhouse-diesel.com\/collections\/thoroughbred-diesel.oembed","provider":"Powerhouse Diesel","version":"1.0","type":"link"}
