Hi Paul,
today I found a 6 port brass valve designed for fuel injected systems for

$245 .

In my case with the CZ MK-IV will solve most of my fuel delivery

problems. It has

Left tank, Right Tank and Off positions.  Since will be mixing oil in the

fuel,

lubrication is not a problem. I don't have to build  sump tank etc.  and the

return fuel will go back to the selected tank. Only extra work will be

running

return lines that will have to be done anyway.
One draw back is that it weighs 2.5lbs. but will save me $200 from the Allen

valve?

Yowee these valves are expensive.  But, this is a seriously important
item, so good quality is important.  I assume the '6-port' means you will
route the return fuel back to the same tank?  If so, this makes fuel mgmt
pretty simple.  Is this a manual valve or electically operated?  A/C or
auto?  ( I assume A/C).  Sounds like a good solution if I understand this
correctly.

You are correct Bill. Per plans I have one line coming from each tank to the valve
between the front seats and than one line going to the engine. With the fuel
injection, I will have 2 lines from ea. tank to the valve and two back to the
engine. I will return the fuel in the outboard part of the tank and will have max.
cooling and mixing of the returned  fuel.
With the sump tank system the return loop is very short, and I will have a fuel
tank just above the main landing gear inside the cabin.
Per plans system is proven and simple, so with this valve I will stay with the
proven system.
About the quality of the valve, I like it. Wish it was a bit smaller, but that's
the smallest they make. It's designed for diesel and gasoline systems. The main
ports are 1/2" and the returns are 3/8"
