No, you are wrong wrong wrong. The crud thing was a P.S in #18. Isn't this where you would post something like individuals should read posts carefully yada yada yada?

Yep, you should read the entire thread, because after he posted the "crud" in his gas tank well, I explain to him in post 19 how the "Crud" got there.

How am I wrong about the fuel pump not being the problem? Oh,I forgot that your solution to anybody with a problem is to pull the plug to the MAF.

No data in that piece. Nothing referring to test cases, number of in the field incidents, not even specific vehicles it could affect.

BTW, I'm not disputing that it DOES happen from time to time. I just believe that when it does it's most likely very close to that particular pump's EOL anyway, and the low fuel level might have just pushed it over the edge. I also think fuel quality over the life of the vehicle has a much greater effect on longevity than fuel levels. But this is just personal belief and experience talking, I am certainly not a scientist.

Don't be so defensive. I said nothing about you being wrong about the fuel pump being the problem or anything you posted other than missing OP's humor. Read #17 PS again-- it had nothing to do with the fuel pump.

I could be offended by your comment about my input if it weren't so childish and obvious to others that is not the case. Check your MAF if you don't believe me.

X5 is not normal: the fuel tank is not like any I've ever heard of. In essence once lower than 60% full it is ALWAYS using the last two gallons of gas. Because of that, there's virtually no chance of any sediment, no chance of a fuel pump that is not submerged in gasoline if you can actually drive the car.

I'm willing to bet another mfg design defect causes a lot of trouble. I will be posting a detailed thread soon describing what I've found when solving my wife's x5 fuel problem

Correct, 'crud' was in the bottom of the tank, and looked like metal shavings. I tried to take some photos, but they didn't turn out very well, and I was freezing, so it wasn't a priority to get a good photo (temps were around 15 degrees, and seriously windy the day I had to change it out).

When I finally drained all the fuel down and wiped it out, it was almost like graphite on the rag..

So for the record, are you one of those drivers that run the gas tank down to almost empty or do you fill up at or near the 1/4 mark? Just want to determine if running the tank down to near empty cause the shaving in the tank.

andrewwynn didn't find any shaving at the bottom of his tank, but it was his wife's car and she believed in filling up the gas tank when the needle showed 1/4. His problem was not a bad fuel pump but a bad siphon pump.

i gallon = approx 4L
therefore 20L of fuel you recommend

I wouldn't draw any conclusions on two samplings regardless of shavings or no shavings at the bottom of the tanks. We don't even know where they came from.
