the fuel rails on my 20B aren't very compatable with designing a low profile
intake manifold.  I would like to saw the ends off.  They appear to have
small diaphrams on them, perhaps for fuel pump pulses?  Are these necessary
for aviation use?
    I assume that I will feed one rail from the pump, off the opposite end
go to the other rail, and from that opposite end return back to a fuel tank.
Can the fuel return T back just upstream of the pump instead with a one way
valve perhaps?   kevin
