Pretty sure I know what the answer will be. My fuel pump has been whiny lately and so I bought a new fuel pump to have on hand. The Bosch pump said it was an improved OE design with a longer service life. That sounded good to me as the last one was only replaced about 8 years 15k miles ago. Also came with the pigtail. https://www.rockauto.com/en/moreinfo.php?pk=978009&cc=1061356&jsn=732 Since then I've seen someone say "Don't buy the Bosch pump", but didn't give a reason why. And a search for 'fuel pump' shows only recommendations for Delco and Delphi. Guessing I should probably return it and get a Delphi or a Delco?
