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 4 hrs before the pump is sent to you. Bosch VP 44 diesel pumps are also upgraded with all the latest upgrades required by Bosch. These VP44 injection pumps come with a 2 yr 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.

A cam ring with three plungers, a rotor, and an electronically controlled fueling solenoid valve is used to develop and distribute the high pressure required for injection. 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.

*Performance chip & add on disclaimer - 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.

hey I just finished building my 1998.5 dodge ram cummins. I did a full engine rebuild,including new cylinder head etc. truck was running good, few days ago I went to fill up the truck, stat seeing blue/ white smoke, my lift pump went out and I drove the truck for 3 days not knowing. the vp44 is not throwing any code. I purchased the truck with the fass pump not hooked up. my question is when the vp44 goes out does it blow blue / white smoke? before I purchased a new vp44 from you guys.

jafin john | 2/29/2024
Yes, it can , please phone and ask for tech support.
does extended warranty add on to the end of your included warranty?

PATRICK PLATZ | 10/25/2023
Yes it adds on to the existing warranty.
Can I send my core and a money order in at the same time? I need pump for a 99 Dodge autowith a Cummins.

Does the pump come with a new over flow valve?

Jerry davis | 4/19/2022
Yes
Will installing a stealth tap cover void the warranty

Zach | 11/3/2020
The stealth cover will not void warranty. As long as we are able to read the PSG.
Can u pick up parts at your warehouse or do they have to b shipped and do u have other prices on your pumps besides the 1 year warranty and 2 year warranty pumps

Billy Dement | 4/6/2020
We are still open for parts pickup, just make sure you call us to verify that we have what you want in stock. On our VP’s, the pricing that we have is for the 1 and 2 year pumps. We do offer some Hotrod pumps as well.
My mechanic smashed the key on my vp44 and tried to get it out after smashing it is it possible for me to send it back to you guys to get the key out without having to by a brand new one

Cordell | 8/17/2022
Yes. Please contact our warranty dept. ext. 271
So if I don’t send back my original vp then y’all charge full price ? If I do send it, it’s only going to cost $750 ?

Gerardo Rangel | 1/19/2020
No, there is no core charge, for the vp44,if you send your core back within 14 business days.

You will get charged $500.00 if you do not return the core.The 2 yr warranty vp44 is $1149.00, 1 yr warranty $975.00.
How Do I Check Lift Pump Pressure to the VP44?

Eric Schumann | 5/16/2019
This method will vary depending on what year your truck is. If you have a 98.5-99 Cummins there will be a 1/8 by 27 NPT port on top of the fuel filter housing. For this year truck, this is the most accurate place to insert your fuel pressure sensor to read the pressure supplied by your lift pump. For trucks ranging in year 99.5-2002 fuel pressure should be checked at the Schrader valve located on the side of the VP44.
What is the Cause Of Hard Starts?

Eric Schumann | 5/16/2019
Hard starts as they relate to VP44 injections pumps are caused by lack of fuel or over pressurization by the lift pump. If a lift pump is going bad and failing to supply the proper amount of fuel to the injection pump, then the truck will hard start due to lack of fuel. However, a newly installed lift pump that is pushing over 15 PSI to the VP44 can also cause hard starts. The VP44 is a very sensitive pump and needs approx. 12 PSI to run properly. Once you start getting about 15 PSI to the injection pump, you actually start to over pressurize the pump causing it to act as if you had a flooded engine.
What Wire Do I Tap on a VP44?

Eric Schumann | 5/16/2019
There are two wires running from the back of the pump up to the computer portion on the top of the pump. This computer portion is known as the PSG. The wire that is closest to the engine and connects to the PSG is the wire that needs to be tapped for installation of some modules. Keep in mind that tapping this wire will void the warranty on your VP44. Thoroughbred Diesel recommends installing a BD stealth cover instead of notching the tap wire directly.
How much Fuel Pressure Should the VP44 Receive?

Eric Schumann | 5/16/2019
There is a diaphragm inside the VP44 that is somewhat sensitive. This particular diaphragm works best under pressures between 10 and 15 PSI. Some pumps will be able to run higher than that but we don't recommend it. After changing your VP44, if you notice continued hard starting or feel as though the pump is getting bogged down, it is probably time to check the lift pump pressure. Our recommendation for optimum fuel pressure is 12 PSI of the VP44.
What caused my VP44 to Fail? Is this a Common Problem?

Eric Schumann | 5/16/2019
The most common cause of VP44 failure is lack of fuel. Dodge trucks 98.5 and up are notorious for having weak lift pumps. Unlike most injection pumps, the VP44 is fuel cooled and lubricated. Therefore, if its fuel supply comes from a weak lift pump, it is very easy for the VP44 to overheat and cause damage to itself. This lack of fuel results in one of two types of failure within the VP44. One is that the diaphragm inside of the pump is damaged and does not allow the pump to build up the appropriate amount of pressure. The second is that the overheating causes the computer portion of the pump to also overheat and thus, creates a communication failure between the ECM and the Injection pump.
