Let me give you guys some info on the BVM High Flow UAT and the associated parts of our High Flow fuel system.
We have addressed the problem and updated the UAT and the remainder of the fuel system to allow high flow by increasing the fitting and line sizes.

Here's the system diagram which can be applied to most other airframes:http://www.bvmjets.com/images/K7300-32_34.pdf

We used my Ultra Bandit as a test bed for the system validation. With the new system, the P200 was very happy, and did not suffer from fuel starvation. The side walls of the plastic bottle did not suck in during full thrust operation when the flow demand is the highest.

Here's another article from the BVM website that is informative: http://www.bvmjets.com/Pages/Tips/FuelSystem.htm
Happy reading!
