				The last time I drained fuel from the center tank sump, the valve did not close completely and fuel continued to drip overboard.  After opening and closing several times, the dripping stopped.  I have not opened the valve since, for fear of it sticking open again.  Has anybody experienced this situation..??  I was unable to identify the valve in my parts manual.  Is it the same in all Commanders..??  I may need a replacement valve.  Anyone have one..??  Thanks.

				Randy,
   
  This valve (the twist valve that you  access through the small door under the wing) looks suspiciously like the Eelco  valve that I used to shut off the fuel in my D Altered 57 Chevy. Drag Car  equipped with early Hilborn Injectors in about 1972.  Meaning that it  was military surplus.  Most likely the valve needs to  be removed and new "o" rings installed.
  You are correct that the valve is not  listed in the Commander parts book, which is a very good  thing..........................
   
  Regards.

				Hi Moe,  
 Thanks for the response.  I think the challenge will be to get the valve removed and the fuel line capped without spraying gas all over the place.  And then re-installing it.  Any suggestions, short of de-fueling the tank..??

				Good Evening Randy,
   
  Just be sure to properly ground the fuel tank to the receptacle into which  the fuel is being drained. There have been many airplanes and aircraft repair  stations burned to the ground during defueling operations. If you use plastic  containers, be extra careful and run a bare copper wire from inside the fuel  tank on down into the fuel in the accepting container. Ya can't be too  careful!
   
  Happy Skies,
   
  Old Bob

				You mean like instantly selling the hangar and plane to the  insurance company?

 Good  Evening Randy,
   
  
   
 Just be  sure to properly ground the fuel tank to the receptacle into which the fuel is  being drained. There have been many airplanes and aircraft repair stations  burned to the ground during defueling operations. If you use plastic containers,  be extra careful and run a bare copper wire from inside the fuel tank on down  into the fuel in the accepting container. Ya can't be too  careful!
   
  
   
 Happy  Skies,

 Thanks    guys.  Good reason to go for a flight to burn up most of the fuel from    the center tank before draining in to jugs.     Randy.

				Neat opportunity to see just how much fuel the ship  might REALLY hold when you refill.
   
  Our 500B took 150 gallons to fill a completely  defueled 156 gallon system once, and 150 gallons another time parked in the  opposite direction at the same pump.
   
  Either we're getting chubby gallons, or maybe we  don't really hold 156.
   
  I guess some folks like the simplicity of all the  tanks draining into one, but I sure sometimes miss having fuel squirreled away  in other tanks on a long drive home.

				I would take the opportunity of an empty fuel system to  clamp a clear hose to the center tank drain, hook the other end of the hose to  the side/top of the fuselage and add 10 US gallons at a time.  At each 10  USG increment verify the indication on the fuel gauge as well as mark the clear  hose.
  Once all of the above is completed you have a calibrated  fuel gauge as well as a calibration hose so when the fuel is down below dippable  range on the wing you still can verify the exact quantity of fuel in the center  tank using the hose, in a sense dipping the tank.
  So if you are from the school that does not trust  electrical fuel gauges then you can still measure (dip) the center  tank.
