Overview:

The APR High Pressure Fuel Pump (HPFP) dramatically increases the maximum volume of fuel the HPFP can deliver. 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 136 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. Upgraded supercharger and turbocharger systems are 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 internal seals are replaced, including the spring seal, and the tip of the pump retains the factory pivoting head to reduce cam follower wear and piston side loading. 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 kit included two new rebuilt pumps.

cute, fun and great for dogs that don't instantly destroy toys
Style: Mummy with Organs
The dog LOVED this toy! She loved it to pieces she played with it so much! The organs and the mummy are very cute. There are a variety of different sound/ textures to the pieces. The zipper was the first thing that broke after enough shaking by the dog. It is neat that you get so many pieces in one toy and that they all fit inside the mummy's belly zipper. It is a stuffie soft toy, so if your dog is a squeaker harvester, this toy will not last long. It is well made though of your dog isn't a toy destroyer. I like that different types of stuffing the pieces have. Some are krinkly and some have squeakers.

Great toy!
Style: Pilot Pig
My dogs love it! Even though they are smaller (~16 lbs), they had fun trying to open the pig up and get to the other toys which are much more their size. I bought a similar one, the mummy, for Halloween and they loved that one too. It's rather durable - thick fabric, well-constructed. I could see larger dogs not destroying it as easily as other plush toys. Would recommend!

Adorable and Fun BUT the Zipper Can Cause a Safety Hazard
Style: Mummy with Organs, Style: Mummy with Organs
My dog is having a blast with this Halloween toy from Nocciola! The mummy is large, soft, and delightfully spooky—such a fun way to spoil your pup for the season. It has a zipper that opens up to reveal all the “insides” you’d expect from a proper mummy: lungs, heart, liver, bone, and more. Each little piece is well made, with some squeaking and others crinkling to keep dogs engaged and entertained. The only drawback I ran into is the zipper. My pup zeroed in on it and managed to chew it off within minutes. Depending on your dog’s chewing style, the zipper could be a concern. That said, the toy is still a hit in our house. My dog loves digging out the little pieces and then watching me put them back so she can start all over again. She also enjoys playing with the smaller toys individually, which gives her even more ways to stay busy and entertained.

Durable, entertaining and quality
Style: Pilot Pig
I got this for my neph-dog and he was OBSESSED. The ability to rip the guts out was exactly what he needed after a long day of being cute. The quality is great and he has been able to rip out its guts countless times, throw a treat or two in there? Yeah that's the best day ever for him. Humor and durability? 5 stars for me
