Overview

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. OEM Components: Critical to the design of the APR HPFP is the use of only genuine Hitachi components, made in Germany, which consists of sensors, pump bodies, and other critical components that must operate with OEM levels of reliability. All APR components are made in the USA using medical grade precision machinery.

Good paper towels.
At the time of my review this set of 16 double layered paper towels are going for about $18.99. Not a bad price for a namebrand paper towel. I usually use Great Value paper towels because they are not only inexpensive but have good absorbency so it was interesting to compare it to the Scott namebrand, whom I use just about exclusively for my toilet tissue. The papertowels worked well as I expected them to but I did not specifically see a dramatic difference between it and the ones I usually used. The only noticeable differences to me were: - Scott paper towels had a prettier pattern - Scott paper towels visually had a much more tidy design and *looked* higher quality - Scott paper towels felt softer to the touch As for absorbency though? I felt like they performed identically. And trust me, we burn through paper towels. We have two small children and still have to wash bottles daily. So, we try to balance cost versus efficacy for papertowels because we use them so much every day. For the what they are these are great, but I will probably stick to the other brand unless I'm in a pinch and need to order papertowels more conveniently OR if these ever go on sale or have a coupon. I don't need my papertowels to look or feel pretty (the sloppy floral print and more coarse feel of the GV ones work for us right now because they are used exclusively for clean up), I need them to absorb and pick up gunk well. Would I still recommend these, though? Absolutely. Maybe appearance and texture are more important to you for a paper towels. We aren't there yet with our littles. Lol.

Just pay for the better ones, these are cheap junk. They can’t even be torn off without falling apart.

MY DOG LOVES IT
Size: 20.0"L x 20.0"W x 6.0''TH, Style: Round, Pattern Name: Bed
MY CHIHUAHUA WON'T GET OUT OF THIS BED! she loves it! from the first moment we brought it in and put it on the floor. she gently scratches at the sides and cuddles in with her blankey and likes she's not there. ohhh... great value for the price! nice size, big enough for both of my chihuahuas to lay in comfortably. soft, but very sturdy sides, the bottom is fluffy, padded very well. the outside bottom, there is a non stick covering so the bed doesn't scootch around on tile floor, it stays put.

It's lasted
Size: 20.0"L x 20.0"W x 6.0''TH, Style: Round, Pattern Name: Bed
I've had this bed for 5 years and it is still in great shape. Washes up in the washing machine just fine. My littlest dog absolutely loves it and is lost when our other bigger dog steals it. She barely fits in it but she loves it too. Ha! Good quality at a good price. Couldn't ask for more.

My Puppy Loves It.
Size: 20.0"L x 20.0"W x 6.0''TH, Style: Round, Pattern Name: Bed
I didn't know what to expect when I saw this advertised, but some reviews said that their puppy had chewed on it and it was still holding up with no holes. So, I decided to get it and see for myself. I have to say that my puppy loves it and chews on it and it is holding up very well. No holes yet and I suspect after all her chewing and no holes, there won't be any. Nice size for a 25 pound dog and smaller. Well built and nice looking bed. It has enough padding to make it soft for my puppy. I got it big enough, so she can grow into it, too. Well satisfied and I do recommend it.
