|Well, the question is why the A1000 failed in the first place. Usually it is because it became clogged with dirt. Did you run filters inline with with both before and after? There are two part numbers, 12304 and 12301, that are designed to work with this pump. It is critical for the pump's health that you run the 12304 between it and the tank. And, it is important for your injector's function that you use the 12301 after the pump.
What size fuel line did you run? The A1000 is happiest with -10AN line/fittings between itself and the tank, -8AN to the fuel rail, and -6AN return line. Relying on the stock lines after the pump could certainly lead to premature failure.
