Review on Hitachi HPP0004 High Pressure Fuel by Marcus Akram

I bought and installed this item 3 weeks ago. Overall it works. But on my A4 2005.5 it should contain an additional valve for the right side. 2005.5 didn't have this valve when I removed it. You cannot install a new pump until the correct valve has been installed. Or you keep releasing the fuel pressure. I had to remove the case and change places. Be extremely careful when doing this. The parts inside the fuel pump will just fall out if you don't. And you will be in a world of pain when that happens. So for the price it can and should be included.
