For parts or to fix 2005 Nissan titan, needs fuel pump 145k miles

Bought in Kingman- seller said it needed a fuel filterthere is no fuel filter on this truckwas the fuel pump. I put a walbro 225 pump in it and it ran real well for about a week, then quit. Either I did something wrong when changing the pump or the pump was 1 of the china knock offs that may or may not be any good, It got up and ran good and would make a good beater or work truck. but I just bought 1 with 1200 miles on it and do not wish to work on this 1. john cell 970-640-4804 text is fine also.
