REFLECTOR: fuel feed - my solutions

[Wayne]

Thanks Al. Since I draw fuel from the nearly bottom of the sump and with a couple of inches of fuel in the tanks I would have thought I had about 15  inches. The pressure in the cabin while flying should be good most of a pound. My alternate air for the airspeed seems to confirm that cabin pressure is higher than static .
Oh well if they don't work  they don't weigh much.Next order from McMaster carr perhaps I will order the 0 psi jobs.

  I'm using two of the .5 jobs for an alternate air source in the top of the loop before the vent line goes to the bottom of the fuselage. If the fuel vent iced over I hope they will provide cabin air to the fuel tanks. If the bird is upside down they shouldn't allow fuel to leak inside the cabin.



  Wayne;



  0.5 psi is equivalent to about 15" head of fuel - which is more than we have- so that check valve will never open.
