Hope it improves gas mileage lol!

I did a fuel gauge reset back in May '22, following the procedures andrewwynne prompted me to use. The thread is here:
https://xoutpost.com/bmw-sav-forums/...c-foxwell.html

Here's a list of what the 21 settings are all about:

Maybe that was the first sign of an old pump & sender about to go out.

I have the low cluster, and the Previous owner lost the MID, somehow.

Mostly it helps recalibrate the fuel gauge that uses a buffer and can get really out of whack when the pump had had problems and replaced.

Thank you guys, for the clarification and additional info!

I substituted a better copy of the OBC LIST into my previous post #41, for easier reading.

Though it was intended for E46 models, it works on the E53, at least in my low-cluster model.

I received the Hella pump today, a day earlier than I expected. couldn't wait topull out the OEM, and install the new pump. That was 2 hours or more ago. I still haven't got the locking ring back on.

I even got the wife to come help me, because of my bad left wrist & thumb, and my entire right arm is getting worse by the day (I know, excuses, excuses), and we finally gave up. Dhe went back to her new living room make-over project, and I'm in my office looking at videos to see what I'm missing, or doing wrong.

I'm making sure that the tab on the upper edge of the pump assembly is going into the slot of the serrated ring, but whenever I'm trying to hold down the pump (it's strongly trying to pop-up), and simultaneously trying to get the locking ring to catch threads, it cocks sideways and I lose my grip.

What am I doing wrong? I've never ever had a problem installing an in-tank pump before, but it's happened now.

It sounds like you don’t have the foot in the notch at the bottom

Also, are you putting the ceiling ring on the pump assembly before installing?

I don't know if it's in the notch in the tank, but this time when I removed the "ceiling ring on the pump assembly" and put it on the rim first, then I was able to start the threads (still using some force to hold it down, but not as much as I had been using), and was able to tighten the pump down (brass drift and BFH).

I watched a YouTube video by TRQ "How to Replace Fuel Pump Assembly 2000-2006 BMW X5" https://youtu.be/asqvlLFTAng, which was the first I saw placing the rubber seal on the rim of the tank. I had installed it before taking it outside for installation. Who knew that it would make such a difference?

The X started right up, no delay, and the fuel gauge needle went straight up to full (not past full as it usually does on a full tank). However, my tank isn't full, so I'm gonna need to reset something. The sender arm went straight in, with no interference, so I don't think there's a problem with it.

[g300d]

Good to see you got it running!

[X5chemist]

Nice! I was about to post the same video. Drive it like you stole it!
Report back the new fuel trims!

The video guy didn't install the new pump!

[80stech]

Yes, the ring goes on the tank NOT the pump. Take it out one more time to check the sender and your work and look for open or short (I think open is full but you can verify that by unplugging the connector) I've never had to reset or recalibrate anything.
