I am currently trying to test my fuel tanks (including fuel line to the wing root) for leakages.



Problem: I want to follow Bingelis' instruction using a balloon at the fuel tank vent. It is quite difficult to seal the fuel tank filler neck properly. How did you do that? Any advice?



Cheers from Switzerland

Martin, I used surgical gloves which really look weird when blown up.  

After putting the entrance to the glove over the filler neck, I took a 

couple of large rubber bands - about 7" in length from bend to bend and 

wrapped them around the filler neck as tightly as possible.  I then 

filled the glove through the fuel line, and had a C clamp near the end 

which I clamped down on the hose once the glove was filled.  Test the 

balloon / filler neck with some soapy water to see if you have any leaks 

there.  If not, enjoy a beer and wait about 2 hours to see whether the 

glove deflates.  If so, reinflate the glove and then start testing 

joints the fuel line, etc. for leaks.  Hope this helps. Robert

Best thing to use is a Condom,

works better than a balloon.
