Hey! A little more respect for your elders {:>).  Back then there were very 
few liquid cooled engines in flying homebuilts at all - NOW  you can find 
"coolant" or "Water" pressure and temperature gauges.

Yes, I have been know to make do with what ever would make it go.  If we 
were logical (according to most folks) we would be flying behind a Lycoming 
{:>).

Trying my hand at the use of a miniature colored graphic OLED display - but 
can't even get the thing to turn on a pixel yet.  So is it the display, the 
controller, my connections or my software? (No answer required)  These 
things have gotten very complicated, taking 15-20 separate commands just to 
configure and initialize - makes programming a chip seem simple {:>)

Ed,
Let's see if I got this straight... You fly an airplane you built in your 
garage, installed a car engine... (sideways), with pistons that go round and 
round instead of up and down (like real engines do),  you're using a fuel 
pressure sender for water, and a water sender for fuel.  Hmmmmm, OK, sounds 
perfectly logical to me.

Mark

Wendell, I used a 0-30 psi fuel pressure sender for my water pressure - 
still working after 8 years.  I also used UMA's 0-30 psi fuel gauge which 
they remarked as "water pressure" rather than "Fuel Pressure".   They used 
to have a Water  pressure gauge  - you might try their web site.

Some DAR's require that you have a valve and can reach it with your seat 
belt on.  I assume an electric one, as Ed mentioned would also do.  JohnD

The control valve could be outside the cockpit and operated by a dash 
mounted pointer with a long aluminum tube shaft through the firewall to the 
valve.

Speaking of fuel valves, the original Cozy plans call for a manual selector 
valve mounted  between the pilot and co-pilot with lines up to the seat-back 
and then to the engine. This setup has several connections in the cockpit 
that can leak.

As far as a fuel shut off valve, I don't plan on using one, just turn off 
the fuel pumps. For maintenance I plan on ball valves out of the tank (ahead 
of the sump tank) and these could be remotely operated.

Thanks to all for the responses on the gauges questions.  I found some 
sources for the VDO units and will look at the suggested ones also.

Any suggestions on water pressure gauge senders? Can't find any yet.

Wendell
