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

I am an ASE certified auto and heavy vehicle technician, I bought this unit for my wife's Expedition 03, after the fuel pump failed. I bought it and installed it on January 11, 2019. It broke down on May 22, 2019, now I have to remove the tank again and redo the work. They say they have a two year warranty but if the pump fails within a year then there is definitely a manufacturing issue. I have been working in this field for 20 years. I will never buy DWVO products again.
