[Land-speed] Cold start valve question

[Skip Higginbotham]

Greg,
I use a primer system not unlike that used on P-51 airplanes.....I 
use an electric pump that pumps around the mechanical FI pump on the 
liner. It takes fuel from the inlet side of the pump and pumps it 
into the outlet side of the pump. It thereby fills the system and 
provides fuel to start the engine. Works fine. (It won't sneeze if 
the throttle remains closed........)

I have a reverse flow check valve and a normally "off" solenoid valve 
wired into the electric pump circuit so that fuel can't be pumped 
back into the pump inlet after the engine lights.

Questions?

Good luck,
Skip
