Leaky Header Tank

[djmc4344]

I may need to change my header tank in my model iv because of a problem leak at the bottom fitting bushing. I think the threads were tapped to deep or I may have tightend to much. My question; is the rotational moulded tank from Kitfox the way to go or are there other options? Does the Kitfox tank have the brass fitting molded in?

Thanks for your opinions in advance, this problem is holding up my first flight.

Dan, Check with John or Deb at Kitfox Aircraft about their aluminum header tank. You get a little more capacity and it is very durable. It also has the built in low fuel sensor. You'll love it and no more leaks in the cabin. I bet they have them in stock and ready to ship.

Recently replaced my leaky molded header with the new aluminum one. Perfectly sealed now. I'd go with the aluminum from the 'get-go'.

Too bad we can't get Aluminum wing tanks, too...

Problem fixed, installed a new Plated steel bushing (sharp threads) applied Permatex 9 AR Tack and Seal. Let it set a few days , no leaks to date. Thanks for all the responses.

My wife and I just got back from Mesquite Airport, working on 703KA. I have been smelling fuel in the cabin, we removed the seat, to check the fuel lines, and found that the header tank is leaking from the two outlets from the pilot side of the tank. The fumes were very strong. When we took the seat up we could see a stain spot on the bottom coving of the plane. It is obiously not a bad leak. However you can see a stain going down the side of the header tank (Pilots Side) and on the skin below the header tank on the Pilots side of the plane. II'll be talking with John Monday!
