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, such as a thicker diaphragm, and
new computers. Our VP44 injection pumps come with a
1yr unlimited mileage warranty.
Thoroughbred Diesel also offers several replacement lift
pumps, that are better quality than what comes from the factory.
If you are placing performance parts on your truck it is highly
recommended that you use a performance lift pump such as the
Airdog or Fass Fuel Systems. A 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.

The
fuel injection pump (VP44) is an electronic rotary distributor
pump. The pump performs four basic functions:
Producing
the high fuel pressure required for injection
Metering
the exact amount of fuel for each injection cycle
Distributing
the high-pressure, metered fuel to each cylinder at the
precise time
Varying
the timing relative to engine speed.
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.
