John,

    

   Theres an O ring in there that probably is damaged, has dirt or a small flake of aluminum keeping it from sealing

   properly. I had to remove one early on that was leaking and just cleaning it was all it needed. I have lexan windows

   and the auto fuel(ethanol) from that drain gets into the rivets there and causes it to crack. This happens when someone

   slams the door up to the wing to get it to attach. Anyway don't let it go and damage those nice bubble doors.

John, I had the same thing. It is the O ring that seals the fuel sampler. I  drained the tank and removed the fitting and replaced the O ring. Make sure that  the O ring is compatable to the fuel that you use.

The "Hints for Homebuilders" guys (EAA website) Dick and Bob Koehler said at a workshop at Airventure that those sampler valve seals are not serviceable.   Cost to replace, around $10.

John,

You might want to lay in a supply of those o-rings.  Happened on both 701s I built.

John:  I had to replace the first set of drains on my 701.  They came 
	


with a black "O"ring and did not last 6 months.  I had to also replace a 

side window cause I left the door up and fuel drained on the window and 

caused crazing.



The ACS part # is 05-01865 and it is called Saf-Air Drain Valve 

CAV-110.  It should have a blue "O"ring.  I have not had to replace any 

of these valves once I installed the ones with the blue "O" ring.

Hey Guys



What is the thinking with regard to why the black O-ring fails, and the blue 

one works? Is this possibly an issue with alcohol in the fuel that is 

deteriorating the black O-rings?

The black ones are probably neoprene which will be degraded by alcohol in  the fuel and the blue ones are probably silicone which is impervious to the  fuel.

I need to buy some all-fuel compatible O-rings for my mechanical fuel pump and my primer.  Anybody got a good source for fluorosilicone (or similar) O-rings that sells in small quantities?

What fuel sampler valve does Zenith supply  these days? 

  

 My samplers, from back in a 2000 kit, are  brass and the kind that you used to see on cars to drain the radiator.  It  has a handle with a hole in the center. When the handle is turned it screws  out and the fuel comes through the hole.  As best as I can see, the sealing  is done with brass against brass, no O-rings of any kind. I have had  one drip and now need to keep it really tight.

What happened to my 701 at the beguining, during the first test hours was that,even that we cleanned the tank well after installing the gas gauge, there was a little piece of aluminum from the cutting that got betwen the valve and the seat, we just got the valve off, saw the tiny piece and cleaned,  no problem since in several years...
