That pretty much describes what the cars I fixed were doing, not always a cracked or torn O-ring sometimes they were just swelled up to the point they didn’t seal I tested the fuel pumps independently on the bench and they made correct pressure, it’s been a while but I believe they’re around 41 psi. I would say the vast majority of these fail for this reason. Kind of a piss her when the new fuel pumps are $400 or something like that, I have no idea what the dealer charges to install.
Interesting, both mine were replaced under the extended warranty. Doubt the dealer techs are even bothering to look into why the failure, just swap out the $ 400 pump, NEXT .
