Also, I have been thinking about the fuel return from the fuel rails

to the

fuel tank.I will have two fuel tanks, I was thinking about have separate
fuel pumps and filters for each tank.

But, after the fuel gos to the fuel rail how to make sure the fuel is
returned to that tank.I do not want to run fuel to the cockpit where

I sit,

as I am building a canard pusher.

I was at a rod and custom auto show last week-end and saw a few rods with
nitrous oxide injection.

They have small solenoids to direct flow to the engine.I was

wondering if we

can use them to direct flow of fuel back to the tanks?

Any ideas?

Quickkit sell a solenoid valve (double valve -- one valve for pressure

and one for

the return line) to its kit builders -- the Glass Goose.

 I do not trust solenoid valves for a critical function like fuel selection.
The problem is that most fuel valves eventually need rework, lube
wears away, o-rings get stiff, etc.  WIth a manual valve you assess
the condition each time you use it, and if it takes a bit more force,
the "bit more" is available (within reason) - you just twist harder.
At some point, you are aware that the valve needs work, and
hopefully, you fix it before you can't switch tanks at a critical time -
like over Monterey Bay at 300 ft..

With an electrically actuated valve, it just stops working one
day.  Probably at the worst possible time and you crashland
with lots of unusuable fuel.   Part of the reason that John Denver
is dead is that the builder of his plane was so worried about
fuel fwd (pusher) of the firewall that he remoted the fuel valve,
leading to a linkage located at the left shoulder point which
requires contortions and the right (control stick !) hand in a
Long EZ to select tanks.  I have heard that the valve handle
had been temporarily replaced with a set of Visegrip pliers.
Valve so stiff it broke the handle?  Don't know.  Apparently
ran a tank dry and failed to control the A/C while struggling
with a poorly located and possibly stiff, non-std fuel selector
design.

I bought a certified A/C (Piper) valve.  Andair makes very
expensive but extremely nicely made fuel valves of many types.
