I can think of a lot of reasons not to do this, but the one that comes to the top of the list is the fact that about 3 minutes into your flight you will likely flameout your engine due to loss of fuel in the UAT.

Not to be a smart ass, but the location of your engine and fuel pump have nothing to do with how and what the UAT does. You can tilt it forward almost to 90 degrees flat, but best is simply straight up and down. A few more inches of tubing will mean nothing to your system.

Good Luck,
