Paul,

   Does it get hot if you run it a long time say at 5 volts?

   I tested the Walbro pump I had to day and it will run
   down to one volt. A good sign for a wide dynamic
   range unlike an electronic fuel injector.

   The 5V volts would be an average. Say a 40% duty cycle of 12 Volts.
   It is a DC motor so I don't think it will over heat. I'll have to check it.
   What scenario are you thinking about? Of course it is fuel cooled.
   The fuel actually flows through the motor around the armature.

Paul,

Being as I know very little about engines, (what the engine needs - GPH
or LPM and what the pump puts out at 5 VDC) et al, say a 5 hour leg at
12000 feet.

The engine needs about 10 gallons an hour plus or minus two depending on
cruising speed. I don't know yet what voltage the pump needs to pump 10 gallons
an hour. I will find that out if I go the PICAXE route.
Right now that looks like the cheapest way to go.

50 mm side draft carbs seem to run $450 and up each. You need two.
You need 50 mm and p-ports unless you want to take a huge hit on the HP.
If you don't care about the lumpy idle a 58 mm side draft Weber
would work fine on the end of two 25 inch long two inch OD  intake tubes
on a P-port engine.

Anybody know what 58 mm side draft Weber carbs are going for?
That is if you can figure out how to lean them.
