Folks,
Any experience with a forward facing clunk tank setup. What I mean is that the fuel stopper is at the rear of tank instead of the front. Would this allow the clunk to become exposed and suck air more often than a rear facing clunk? NO LEAKS IN THE UAT. The air IS coming from the main tank. I can run up the turbine for 5 minutes and not one bit of air gets into the UAT. I go fly for 3 minutes and the UAT is 1/3 full of air.

Any thoughts or comments? Any one with similar setup that can adivse. NO guesses please....To much invested for that.

Dave
