*Wire Tap Voids 1 Year Warranty*
This pump is built with a reman PSG and reman aluminum housing
VP44027P 1998.5-2002 235HP pump that will fit Dodge Cummins Turbo
Diesel with Automatic or 5-speed 215HP & 235HP Dodge 5. Most common
pump found on Dodge Pickup Trucks. Can support 650HP with the proper
supporting mods. Pumps are rebuilt by a certified Bosch shop and have
all Bosch upgrades and updates including new electronics and steel
housing. One Year/ Unlimited mile warranty.* The VP44 is the most
advanced pump Bosch has made. It uses the computer or PSG to control
both fueling and timing. It is also more sensitive and dependent on the
lift pump for cooling and lubrication. If the lift pump fails or is
unable to keep 5psi (recommended is 13psi) of fuel pressure your pump is
susceptible to damage, overheating and failure. Free shipping and
return shipping to 48 states.
Core:
Core deposit
of $600 required unless core sent in advance. If a rebuildable core
(ie. not seized, damaged, contaminated, disassembled) is not received in
30 days from date of shipment a reduced core credit of $200 applies for
late cores. International orders have 45 days. IF YOU PURCHASE AN SO
235HP PUMP, YOU MUST RETURN AN SO 235HP PUMP. ANYTHING OTHER THAN AN SO
235HP PUMP RETURNED WILL RESULT IN 1/2 CREDIT.
Shipping:
Free
shipping on the pump and Free return shipping of the core for 48
states. HI, AK, PR and International orders do not qualify for free
shipping or a free return shipping label.
VP44 DISCLAIMERS:
Failure
to replace feed pump along with the Injection Pump may result in damage
not covered under warranty. It is highly recommended that the feed pump
be changed along with the injection pump. The VP44 pump uses fuel to
cool and lubricate the pump. The tolerances between the head and the
rotor are very tight. Performance chips 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/tapping into the pump
wires is to use a larger set of injectors or/and 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.
Troubleshooting:
Often
if your VP44 failed, the root cause is a bad or failing lift pump. The
stock lift pump does not supply sufficient pressure for stock power. It
is mounted to the engine block and has to push through some small
fittings and lines that act as a restriction, even worse the pump has to
pull fuel all the way from the tank. Electric pumps are designed to
PUSH not PULL fuel. The in tank pump recommended by Dodge dealers is not
much better. It may flow a slightly higher volume but at pressures even
lower than the stock pump. It is placed inside the fuel tank to keep it
cool and reduce failures, but when it fails you are out another $500
for the dealer to drop your tank and replace the pump again.
Defective VP44 Codes:
The
retrieval of codes does not constitute an engine diagnosis. However,
there are some codes that usually indicate a defective injection pump. A
current P1688 always means that the pump is bad, there is no further
diagnosis required. Code P0216 is probably the most common code for VP44
Pumps. If transfer pump pressure has been checked and is O.K., the
injection pump is defective. It is rare to get a P0216 for contamination
but it may be worth trying some quality diesel fuel cleaner/conditioner
with the small percentage that it may clean the internals of the pump
to remove varnish and allow the pump to time fuel delivery correctly.
Other codes that are less common are P0180, P0181, P0215, P0251, P0252,
P0253, P0254, P0370, P1287, P1689 and P1690. These codes USUALLY, but
not always indicate a defective pump. There are wiring and power checks
to be performed if these codes are present. These codes relate to Dodge
pickups only, and are not for any other ISB application.
