REFLECTOR: [VOBA Forum] Fuel line routing

[Velocity Aircraft Owners and Builders list]

 I took a different approach.

I installed an "NO" (Normally open) Solenoid valve at the exit from each
strake tank and a mechanical shut off valve between the sump and the
firewall. When the solenoid valve is powered, it closes. without power
(normal position OR FAILURE) it is open. They cannot fail closed.

There is a horizontally mounted rocker switch mounted on the panel Labeled:
LEFT ONLY---BOTH--RIGHT ONLY. When you select a tank, the opposite side
valve is powered. The intent is to fly with the switch in the "BOTH"
position, the majority of the time.

The mechanical valve is connected via a cable to the panel where there is
an actuator labeled "FUEL SHUT OFF-EMERGENCY USE ONLY". Pulling this will
close the valve. The cable is not intended to re-open the valve in flight
(although in reality, it seems to be able to move the lever enough to do
so).

Now that I am flying (I LOVE SAYING THAT!), I have found that this system
is logical and reliable. In the first 5 hours of test flying, where I
needed to stay within gliding distance of the airport, I was doing a lot of
circles and therefore developed a fuel imbalance during the flights. I just
selected the tank with the excess fuel until they were even. Worked great.
Photos show panel (before labels), Upper right knob is pull cable for fuel
shut off. (want to change to red knob). Horizontal switch with out switch
cover is for tank selection.
Solenoid valves are the 2 upright brass valves mounted above the sump tank
on the aluminum bracket.
