OK, what'* going on with my EFI pump?

Either someone has surreptitiously installed a Holley Blue fuel pump in my '99 K-engine Bonneville, or the factory EFI pump is making noticeable noise when it didn't before.

Getting ready to fail? How hard to change? No codes.

How loud is it? Its normal to have some noise... But not loud... If it has gotten that bad then you may want to check the fuel pressure before it has the chance to fail on you... The Fule pump for the Vin K is actually larger than most I have seen... And a bit costly too... I think its $130 for an AC Delco replacement..

I guess the best answer to "how loud is it?" is that I never noticed it before but now I do.

Car runs very well and just passed smog, so it must be functioning OK now. But when mechanical things begin to make noise, I worry. :?

Seem to loose a couple of PSI every year... I need to swap the pump out in the near future...
