I'm getting ready to replace the original fuel pump in my '2000 F 150 and was curious if any brand seems to work better or last longer than another. I believe the stock unit is a Delphi and they are a little higher in price than a carter or an airtex, but I am looking for the best pump available in terms of reliability regardless of price. The truck has not been modified in any way so there would be no advantage to a high perf. pump. Which is best? thanks 3d
