Does a 2003 Cummins have a lift pump?
The factory fuel system on your 2003-04 5.9L Dodge Cummins consists of your underbed fuel tank, fuel/lift pump, high pressure CP3 injection pump, and electronically controlled injectors (simplistically put). Until 2005, the pumps were mounted on the drivers side of the block behind the fuel filter.
Is a lift pump the same as a fuel pump?
Modern fuel pumps allow automobiles to operate at higher speeds and improve fuel economy in cooperation with a fuel injection system. Lift pumps add to that system by helping raise the level of fuel into the engine block by creating suction and managing air flow.
What are the signs of a bad injection pump?
Symptoms of a Bad or Failing Diesel Injection Pump
- Engine may run roughly, or not at all.
- Hard starting.
- Engine misfires.

Does a lift pump replace fuel pump?
Lift pumps are not located in the tank – easy enough to replace any time. The “fuel pump” you are referring to is the injection pump which distributes fuel to the injectors, also known as the high pressure pump.
What are the benefits of a lift pump?
The lift pump reduces the effort that has to be made to pull the fuel all the way from the fuel tank. Having a lift pump can extend the lifespan of your engine, especially since it reduces the stress on the injection pump or injectors.

The “CP4” injection pump, as it’s called by many, is the heart of these diesels, and in the past few years it has garnered a reputation for catastrophic failure, resulting in repair costs north of $8,000.
How likely is CP4 failure?
Epic Fails While supplying high-pressure fuel is an injection pump’s job, the CP4 does so with a high probability of failing (typically around the 100,000-mile mark) and leaving owners with a need to overhaul their truck’s entire fuel system, at a cost that can be anywhere between $8,000 and $10,000.
Does Ford still use CP4 pump?
A new CP4 installed in still a CP4 with the same design flaws (when used in conjunction with ultra-low sulfer diesel fuel madated in the US) that have existed since CP4s arrived in the Super Duty trucks in 2010. It’s not been fixed. It’s still the Bosch CP4 high pressure fuel pump.
What is the CP4 pump?
The high-pressure pump CP4 delivers the fuel into the connected rail under high pressure. The CP4 consists of one or two high-pressure elements, each integrated in a housing with its own camshaft.
What causes CP4 to fail?
Why Does it Fail? The problem with the Bosch CP4 pump, according to a recent fuel pump class action lawsuit, has to do with the sulfur content of diesel fuel made at U.S. refineries. U.S. environmental regulations limit the amount of sulfur allowed in diesel intended for the domestic market.
Does insurance cover CP4 failure?
The only way to effectively fix the problem at hand is to replace the entire fuel system. Decision: Because the customer put the DEF fluid into their fuel system on accident, it is treated no differently than you crashing into someone.

Which insurance companies cover contaminated fuel?
Allianz, NRMA & GIO will cover the costs but it’s best for motorists to check their individual insurance policy. Contaminated fuel continues to be an issue affecting thousands of motorists each year, leaving them out of pocket for repairs and without a car for everyday tasks.
