I plumbed an electric fuel pump in parallel to the mechanical hilborn pump,
through a check valve and up to the T by the barrel valve. This allows me
to prime the dry system with fuel until the mech. pump catches up, then I
shut off the electric pump. It also allows the tank to be verified as empty
by simply disconnecting one line. Also it helps in tuning, If I'm shootin'
ducks I can hit the switch and it will richen the mixture and I'll know that
I need more fuel; conversely if it makes it worse then I need to go to a
bigger pill.
