Is the clunk supposed to come back to the front of the tank? My fuel line is too stiff for that. Is there special fuel line that you put in the tank? I always thought that the fuel line bending over in the tank would pinch it.

The 10 second test was at idle and the fuel line did go dry, so it sounds like I have a major issue that needs to be resolved before I fly.

The plane is really to small for a header tank so I don't think I'll go that route, what is a blader tank? I've never heard of that before.

Thanks for all the replys,
