A High-Pressure Fuel Pump (HPFP) is a mechanical system, driven by a camshaft. Unlike a regular fuel pump, the HPFP is able to provide this bigger engine with enough fuel to run sufficiently. The high-pressure fuel pump uses a solenoid to control the volume and pressure within the pump.

How do I know if my HPFP is bad?
Symptoms of a high-pressure fuel pump failure are:
- Delayed start of the engine.
- Hesitation or sputtering in acceleration between 2000 RPM to 4000 RPM.
- High engine temperatures.
- Vehicle stalling due to exertion or temperature.
- Fuel pressure gauge reading low measurements.
- Poor gas mileage.
What does a HPFP do?
The high-pressure fuel pump (HPFP) is a cam-driven fuel pump that provides over 1500psi to the direct injection fuel injectors in your engine. As you can see on the dyno chart to the right, the factory fuel pump is out of fuel much earlier than the IE HPFP.
Does a HPFP increase HP?
The APR High Pressure Fuel Pump (HPFP) increases maximum volume of fuel the HPFP can deliver by 41% over stock! In doing so, the direct injection fueling system is capable of satisfying fueling requirements set forth by high horsepower setups.
How much does it cost to replace a high pressure fuel pump on a BMW?
One high pressure fuel pump can cost about $3,000. BMW claims this defect only affects around three thousand vehicles. If a recall was issued they would have to replace all the defective pumps.
What happens when HPFP fails?
A failing or failed high-pressure fuel pump causes a limited flow of gases to the engine block. When this occurs, the engine is unable to function properly, thus leading to limp mode activation or even a stalled-out engine.
What happens when a high-pressure fuel pump fails?
When the fuel pump fails completely, it will not be able to inject fuel into the combustion chamber at all. This will automatically lead to a complete stop of the car since no fuel will be reaching the engine to run it.
How much does it cost to replace HPFP?
And if the HPFP fails during that extended warranty coverage period, BMW will replace it with a newer-production version at no cost. If your car already has more than 120,000 miles on it then it would not have covered it and therefore you are charged $849 for the repair.
How long does a high pressure fuel pump last?
It takes gas from the gas tank and sends it to the engine so your car, truck, or SUV can start and run. Your vehicle’s fuel pump should last at least 100,000 miles or more. If it doesn’t, or if you’ve exceeded that mileage milestone, you may notice any of the following seven signs.
How do you prevent HPFP failure?
When the HPFP fails, it sends fragments of metal through the entire fuel system, necessitating replacement of every component, with exception of the gas tank. To help prevent this issue, ensure you are using only diesel fuel, and highly trafficked gas stations.
How much is a high pressure fuel pump?
The average cost for a fuel pump replacement is between $220 and $1,062 depending on vehicle and age. Labor costs are estimated between $124 and $260, while parts are priced between $95 and $854. Estimates do not include taxes and fees.
