Subject: Re: Out of Fuel (header)

Bob,

I normally run at 7 gph and pump for 5 minutes at xx:25 and xx:55.  
Therefore I must be pumping about 7 g per 10 minutes or 42 gph. I vary  
the pumping slightly from 4 to 7 minutes based on my flight and fuel  
burn conditions and on the header tank gauge.

As far as your question as to how long it took to get fuel into the  
tank, my answer was that I didn't lose any altitude. It took less than  
a minute for the engine to run smoothly. Remember though that this is  
an engine with a carburetor. A fuel injected engine (as was Chris  
Zavatson's experience) could take longer to develop solid fuel pressure.
