About three weeks ago my car would only fill to about 7/8 of the tank. Each fill up since then has been the same. It does not appear to be the gauge, as the miles per tankful has dropped as well (mpg has stayed the same). I have not changed gas brands, used any additives and have had no other recent work done on the car. Any ideas on why this would happen and how to fix it?

 

I'm struggling trying to locate the tank valve. Do you work on Mercedes? I work in Westminster, just near you in FH.
