Hot start problem

It is my understanding there is a fuel return line at the Injector fuel control unit. By running the pump(s) with mixture closed it does circulate the fuel to the control unit and back to the tank.

This action can eliminate any air and hot fuel in the lines over top of the engine. I understand this is regular practice for the P versions and comes from a well qualified source. It has worked for me in the pass.

Recommended time is not less than two minutes and not more than four depending on temp and length of time on the ground.

The lines on my AC are insulated (that run over top of the engine). I think this was standard on later version.

Since the fuel lines from the spider to the injectors are rather small and contain little fuel, normal priming of the engine clears these rather quickly.

I double check this when I get back to my notes and manuals.
