Review on DWVO Fuel Pump Review: Compatible with 2003-2004 Ford Expedition V8 5.4L - A Reliable Performance Booster by Shedrick Roach

Bought this pump on 18/12. About a week later my wife complained and said the pressure gauge wasn't working, there was a red flag right there. 5 months have passed and this pump is dying. I would say maybe I was just unlucky and got a defective pump. But judging by all the other reviews I would say this product is poorly designed and I would only have a refund. I refuse to get a replacement and spend another $300 installing it only to have it happen again in less than a year. How can I get a refund?
