I imagine you're dealing with O'Reillys? I work for O'Reillys, we just started carrying Precision pumps about a month ago. I haven't heard any complaints on them yet, but I would be leary as they use Airtex part numbers. I would venture a guess that they are just relabeled Airtexs, atleast the first few batches. I like Bosch or Carter personally, Delphis are also supposed to be good. I would avoid Precision for now, just my .02.
