140DZ Inverted Problem
My 140DZ 18x8 Mejzlik turning 8500 rpm on 30% CoolMaster. Great power great idle. When I fly inverted the engine sputters like its not getting fuel when I roll back over she runs fine. I have a Tetra bladder tank installed set back about 10" on the CG. ????????????

RE: 140DZ Inverted Problem
Dave,
This was the first bladder tank I have installed. I must say that it sucks out every ounce of fuel. It has two lines a vent line and the fuel feed. I cut a tee into the feed to fill with a fuel dot. I have the vent line plugged all the time only remove it to fuel up and when fuel comes out I plug it to fly. On the side of the tank is a vent or spill line if the bladder breaks ? Not sure here which is plumbed out and down that is not plugged.

Where is the end of the pickup line in the bladder? Is it stiff or flexible?
Have you flipped the airplane over and observed the fuel line into the pump for bubbles. If it bubbles inverted, you either have a leak in the line or the bladder.
