Changed your FUEL FILTER Lately? (filter cut open pic)
I had a little stumbling the other day on the highway. No SES light, but I did pull a Peake code "81" - which is "lack of fuel".
Replaced the Fuel Filter today. Some have mentioned that BMW says the OEM filter is good to 100K. Uh, I beg to differ as is evident on mine.
With merely 51K miles on my M5, I removed the STOCK (date stamped) fuel filter and replaced it with a new one (HENGST). (p.s., guys this is a easy job!)
I did the ol' blow test which really took A LOT of pressure to get air flowing. Of course there is gas saturated in the filter, but I feel strongly this restriction was more than just normal saturated gas in the filter element. I broke out the hack saw and Dremel, and opened up the stock filter out of curiosity sake). I am fairly certain the filter is NOT supposed to be black. A mere rub with a paper towel showed some real crap!
Something else I noticed is the tweaking of the element. That can't be healthy and probably assisted in the restriction (one would assume).
-QUICK FUEL FILTER CHANGE:
1) Jack drivers side, support vehicle for safety
2) Remove plastic cover shield under the car
3) Relieve fuel pressure (A- press. reflief valve)
4) Unbolt (2) 10MM clamp bolts
5) Loosen filter at NUT end, 19mm wrench on the filter, 24mm wrench on square regulator
6) (B- other end of filter) push in white pressure clip, pull filter out
7) Install new filter ( with NEW copper crush washer) and by reverse of above (mark date on new filter)

Good, simple writeup and pics, but you have to be kidding me on the "support vehicle for safety" part. It looks like all you got is an extra tire/rim sitting under there to 'catch' it. Tell me you took the pic before putting in actual jack stands?
Coupla questions: where'd you get the filter, and how much?
Also, I wonder if this has something to do with the quality of the gas used.
Filter and copper crush washer was purchased at AutohausAZ.com $37 for the filter (part # 13321407299), some cents for the washer.
The fuel is purchased at Chevron or Sinclair. Some years ago, an independant company here in SLC did a gas quality survey. These two rated at the top along with Tesoro, which is something else. I'm pretty anal about putting good gas in it. I am fairly certain the previous owner was too (came from CA and FL before that).

Relax, relax, everything is all fine and I wasn't underneath the vehicle completely. What makes you think that wheel and tire wouldn't save my butt?.

Its not the wheel under the car part that worries me, ( I have been guilty of that when alternative not available.) its the hack sawing into a metal container where there are gas fumes part. Can anyone say boom? Aluminum or not, you wont find me sawing on anything full of gas fumes.
I do appreciate it though, as I wondered how the inside of my fuel filter looked when I made my change around 45k.
