What does HPFP mean? HPFP = High Pressure Fuel Pump.24 Sept 2010
What is a HPFP? 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? When first starting the car, you’ll most likely experience either stalling, hard starts, and trouble running right. You should get a check engine light and codes will lead to the HPFP. I hear there are specific codes indicating that’s what is wrong. You may also get misfire codes.
Does a HPFP increase HP? The Ultimate High Pressure Fuel Pump (HPFP) Upgrade is Here!
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 long does HPFP last?
How long they all should last? No one knows, but there are many stock ones lasting over 150k miles. Like I said before, usually its failure is when fuel is leaking passed the retainer nut seals or regulator issues. Either of those failing causes hpfp replacement and its longevity differs with everyone’s.
What causes high pressure fuel pump failure?
No lubrication from appropriate oil levels causes friction in key mechanisms, damaging the fuel pump and necessitating repair. A reduction in lubrication from the oil will also result in rising heat levels, a symptom that can lead to resistance of the fuel pump motor and ultimately, failure of the system.
How much does it cost to replace 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.
Can a fuel pump go out without warning?
Fuel pump failures often occur without warning. Fuel pump failures can be caused by electrical faults, old age (wear) or fuel contaminants (dirt, moisture or bad gas). A good pump also can’t deliver normal fuel pressure if pressure regulator has failed, the fuel filter is clogged or the fuel line has a restriction.
Will a bad fuel pump throw a code?
Bad Fuel Pump, Fuel Pressure Sensor Can Trigger ‘Check Engine’ Light, P0087 Code. The light is part of your vehicle’s on-board diagnostics (OBD) system and can indicate anything from a loose gas cap to a major repair like a catalytic converter.
What does an upgraded HPFP do?
An upgraded HPFP is capable of flowing a larger volume of fuel than the stock pump. On the EA888 engine there’s a high-pressure fuel regulator that allows the ECU to control fuel pressure.
What is the HPFP problem with BMW?
High Pressure Fuel Pump Failure (HPFP)
The HPFP feeds fuel through the injectors, which directly supplies the engine with gasoline necessary for combustion. If your HPFP fails, your engine will not get the fuel it needs to run.
What causes high fuel pressure?
Causes of High Fuel Pressure
As we discussed, high fuel pressure means that the air to fuel ratio is off-kilter. The causes for this imbalance of fuel pressure typically include either a bad fuel regulator or a clogged return line.
How much is a fuel pump for a BMW?
How Much Does a BMW Fuel Pump Cost? A replacement fuel pump for a BMW vehicle can cost anywhere between $40 and $2,150.
What controls a high-pressure fuel pump?
This pump is driven off a lobe on the camshaft. This part of the fuel system is called the high-pressure side. The pressure from the high-pressure fuel pump is monitored by the Powertrain Control Module (PCM) through a sensor and can be modulated by changing the volume of fuel entering the pump inlet.
Can a high-pressure fuel pump be cleaned?
If your vehicle has an electric fuel pump, you can use a fuel system cleaner to clear any sediment buildup or blockage. If you have a manual one (usually found in older model vehicles), you can actually open the pump to clear debris out of its internal filter, though that isn’t an option in most modern vehicles.
Where does high pressure fuel injector deliver fuel?
Explanation: Most diesel engines use a high-pressure fuel-injector system that will deliver pressurised fuel directly into the combustion chamber of the engine. This system is known as a direct-injection engine.
What happens if fuel pressure is too high?
Too high of pressure may result in, over fueling of the engine. As a result, this can lead to a rough running engine; poor fuel mileage, and black smoke coming from the exhaust. If your regulator is going bad, your car could display several different symptoms.
How do you check a high-pressure fuel pump?
You can use a fuel pressure gauge to verify that the high-pressure fuel pump is the main issue behind the difficulty in acceleration and going uphill. This tool can be purchased at any store that sells car parts and tools. The fuel pressure gauge will be able to tell you if the pressure is too low.
How long does it take to replace a high-pressure fuel pump?
The labor to replace the in tank fuel pump and the inline fuel filter that should be replaced with the fuel pump will take 4 to 5 hours labor.
Can I drive with a bad fuel pump?
So, if your fuel pump is faulty, is it safe to drive with a faulty fuel pump? ”It is not safe to drive with a faulty fuel pump because when a fuel pump is faulty, it can no longer supply the fuel system with constant fuel pressure and your vehicle won’t start, it can stall, or even completely shut down at any time.
Will injector cleaner fix a misfire?
Will injector cleaner fix a misfire? If your engine misfires due to unbalanced air to fuel ratio because of clogged fuel injectors, then yes, injector cleaner could clean the clogged fuel injectors and restore the air to fuel ratio.
Does Golf R have port injection?
The turbocharged direct gasoline injection engines of the EA888 series all have complex innovative solutions such as water-cooled exhaust gas channels running through the cylinder head to the turbocharger (to efficiently reduce full-load fuel consumption) and a dual injection system with direct injection and multi-port
Is a GTI direct injection?
Grand Touring Injection is a type of direct fuel injection which Volkswagen first deployed in the Volkswagen Golf GTI of 1976!
Will a car run with a bad fuel pressure regulator?
A bad fuel pressure regulator can create a difficult to start or ‘no start’ engine. If the ECU can’t measure the excess fuel coming through the fuel pressure regulator vacuum line, it will usually cause the engine to run rich (too much fuel). When the engine is hot, this can make it harder to start the engine.
How do you lower the pressure on a fuel pump?
A somewhat simple option would be to bleed fuel back to the tank. Add a TEE and adjustable valve to send unused fuel back to the tank, and adjust the valve to regulate the pressure developed. The pressure would fluctuate a bit as the float valve opens(lowering) and bump back up a smidge when the float valve closes.
