Fuel plumbing for Andair valve

[Jesse Jenks]

I am trying to figure out a preliminary plumbing plan for the
between-the-seats area. I want to use an Andair valve. I will have a center
console between the seats to cover the controll cables. At this point I see
2 placement options. One would be horizontally mounted on top of the
console. This may be a tight fit with fuel lines and cables in a 4" wide
console. I will also have the hydraulic pump between the seats aft of the
console. Option 2 is to mount the fuel valve vertically, below the
instrument pannel, on a center pannel that would connect the instrument
pannel with the center console. This would put the valve about 8" off the
floor, come to think of it, either option will raise the valve up from floor
level. So my question is how is this going to effect fuel and water flow in
the lines? I assume with all the head pressure from the wing tanks, the fuel
will not have a problem flowing up hill a bit from the floor before going
forward to the firewall. I will have low point drains between the tanks and
the selector valve, so the vertical section of plumbing shouldn't be a
problem for water draining. Am I right to assume any water forward of the
selector valve will drain forward to the gascolator and be taken care of
there (assuming the line has a down slope as it goes forward)?
Thanks
Jesse
