Title: Pump failed after only 7.5 engine hours
Review: Pump came with good instructions. Pump installed easy enough and initially ran great. Pump diaphragm failed after only 7.5 engine hours. Diaphragm torn, and metal diaphragm disk cracked and separated from the the operating shaft. Pretty sure that because the pump was installed and is now contaminated with gasoline (plus I had to disassemble it to validate the failure mechanism), it is non-returnable.
