Hi all,
I posted a help needed on this issue before, but now I have a photo. I got the header tank out without leaking a drop of fuel even though it was half full. The secret you ask? All the inlets and outlets were plugged solid! And I removed the semi-rigid rubber fuel line on the right side. At one time the builder opened the hangar door to find a puddle of fuel and an empty R/H wing tank. Since then it has set for ten years. So now I'm looking for a leaking tank problem. I've been told to do the balloon on the cap vent, but take a look at the photo and tell me if those fittings look ok to you.
Thanks,
Jay
