Bernie:

I am building my fuel system with  a amall bypass orfice around the fuel pressure regulator.  This will allow the pressure to bleed off after the pumps are off.  Does your system have the bypass?  I'm understand we need the bypass to assist in repriming the fuel pumps when they may have been on a tank that was run to empty.

Hi Dennis,

 

The orifice is probably a good idea, but I do not have one.  Have run tanks dry in flight ( at safe altitude) and the pump immediately flows fuel from the new tank. Also have never used the fawcett boost pump to start pumping fuel to a dry system.
