Default Fuel Pump Noisy

It's a little noisy in my 93 XJ but I don't know if I should be worried or not. It runs fine and it's not super loud or anything but you can hear it pretty good. I've heard that it can be a bad ballast resistor but mine looks fine and starts fine so I don't know.

They were never entirely silent. (when they are, that's when you have a problem, lol).
Did you pull the carpet in back by chance? That seems to amplify the FP, turning the back floor into a big resonator.

Keep a close ear one it.

If the pump noise continues to get louder, that usually signals impending failure.

Some of the gurus here can see around corners. Let's hear from the OP.

No I am not Flintstone but it was louder before and I changed the fuel filter and it was silent for about a week. And then it went to how it is now.

All's good 88!

This is as good a spot as any to bring up a question, and maybe an answer. Is there a pin in the tank, and a socket on the pump assembly that should be fit on that pin before the lock ring goes on?

The first time I did mine I was on the side of the road laying in a puddle in the rain. (did not notice, or care about any pin). I pulled it some years later cuz the gauge sticks on 1/4 tank 1/2 the time. Working the float with it out, gauge read fine. Put it back, same result.
I wonder if it could buzz, make noise if that was installed, "just wrong", (almost touching)
