The Honda engine and AR pumps are all good quality stuff. I would give it a 5 star rating if they wouldn't offer the false 6 year warranty which 100% of the time they will try to get out of backing up the warranty.
One could argue that the end user will be the cause of the failure. After the first year if it don't fail it don't have a manufacturing defect. Although they claim the VX20305D has 2950 psi the pump is a RCV 3G27. Which translates to 3 gallon 2700 psi pump. And from our experience will only have 2700 psi working pressure. The same goes for the Opti 4 oil. The engine will not have any manufacturer defects after the 3 year Honda warranty .
