APR High Pressure Fuel Pump - 2.5 TFSI (Rebuild)The APR High Pressure Fuel Pump (HPFP) increases maximum volume of fuel the HPFP can deliver by 30% over stock! In doing so, the direct injection fueling system is capable of satisfying fueling requirements set forth by high horsepower setups. This is accomplished by increasing the displacement of the pump using high quality components to exacting tolerances. How the direct injection system works: A low pressure fuel pump (LPFP) in the fuel tank

The APR High Pressure Fuel Pump (HPFP) increases maximum volume of fuel the HPFP can deliver by 30% over stock! In doing so, the direct injection fueling system is capable of satisfying fueling requirements set forth by high horsepower setups. This is accomplished by increasing the displacement of the pump using high quality components to exacting tolerances.

How the direct injection system works:
A low pressure fuel pump (LPFP) in the fuel tank delivers fuel to the high pressure fuel pump (HPFP) at roughly 4 to 6 bar. Fuel pressure is then bumped up to a maximum of 145 bar, depending on factory parts, with the HPFP. Finally, high pressure fuel is delivered to the injectors, which spray directly into the cylinders.

The problem:
The volume of fuel the HPFP pump can displace is directly tied to the displacement of the pump (Internal bore size, and camshaft dictated stroke), and engine speed. The pump is driven off of a camshaft. Even the factory turbocharger is capable of taxing this system, especially in the mid to lower RPM range where fuel volume is lower.

The APR solution:
We dramatically increase the volume of fuel the HPFP can displace at every RPM by increasing the displacement of the HPFP. This is accomplished by increasing the bore diameter of the pump's internal pressurizing cylinder. It's important to understand, despite the name, a HPFP upgrade is not necessary designed to increase the engine's fuel rail pressure. The primary goal is to increase the volume of fuel available, which will keep fuel pressure steady even in the most demanding of situations!

High quality components and extreme tolerances:
The HPFP internals must be machined to extreme tolerances and installed in a clean environment or the pump can easily fail. Dimensional tolerances on the APR HPFP are as tight as .00004" and geometric tolerances are as tight as .00005". The plunger and barrel are created from certified and heat-treated bearing-grade stainless steel and the plunger undergoes a special diamond like coating process for exceptional surfaces hardness and ultra-reliable operation. To prevent float associated with altering the plunger's mass, APR supplies each unit with a properly specified spring. All necessary internal seals are replaced.

Internal testing:
All APR HPFPs are assembled in house under strict assembly guidelines. Each pump is then tested on our test rig to ensure the pumps operate as designed. This step is important for several reasons. It's critical in determining if a pump has a failure from incorrect install, a leaking seal, or a bad solenoid. Secondly, a seized pump on the vehicle at startup can cause damage to the engine's camshaft. By testing each pump, we all but eliminate these possibility.

Proven track record:
APR pioneered HPFP upgrades in the early days of VAG direct injection engines. Soon after, APR became an OEM supplier of HPFP and GDI components to VAG for use in various race cars, racing series, project cars, and concept vehicles. The APR HPFP has been at the center of countless motorsport victories across the globe and has operated with a nearly perfect tract record since the program's motorsport backed inception in 2006. With tens of thousands of pumps sold, APR has a wealth of knowledge, and manufacturing expertise necessary to deliver a product that will and has stood the test of time.

This is a rebuild of your factory HPFP. Working pumps must be sent to APR.

100% Puppy-Approved
Flavor Name: Beef, Size: Small
My little fur baby absolutely LOVES this!! ❤️ He immediately got the zoomies when I gave it to him. 🤣 It's his new favorite chew toy and keeps him occupied for long spans of time while inside or outside of his crate. Very durable, smells pleasant, and is the perfect size for my small puppy (he is currently 10 lbs and I got him the small one). Previous chew toys that I purchased were too large/heavy for him to pick up, but this one is lightweight and perfect! I highly recommend! 🙌🏾

Not destuctable
Flavor Name: Peanut Butter, Size: Medium
This is the first toy that none of my dogs have destroyed. It's still going strong and they love carrying it around and gnawing on it every day. The material is durable and the product is the perfect size. I will buy more soon.

My 2 German shepherds love these good quality last a good bit
Size: Large (Pack of 1)
I buy these for my 2 German shepherds. My male is a heavy chewer and he will spend time with this everyday until he starts to wear it down or makes it into a makeshift shank and I replace it Last about 3-4 months for aggressive chewers. Highly recommend (keeps them from chewing my stuff)
