[Bob Pastorello]

It stops overflow from sliming the plane.

  Bob,
  Do you find that necessary or is it one of those things that you feel comfortable doing, from experience.

    That's what I've started doing - using the check valve on a "T" in the vent line.  T exits fuse side, leave it unplugged when fueling and sitting.  Plug just before takeoff.  Tank then vents by drawing through check valve.

      Could you use a one way check value that air to enter the tank or is the idea to let air exit the tank?  I assume it is to let air enter the tank to keep it from crushing itself from the pressure that is created from the pump pulling the fuel out of the tank.  I am also thinking about installing a perry pump to replace the regulator that I am using now.

      Ron,

      Vent to atmosphere through the same line that you would normally run to your muffler, the line that has the internal tank tube that normally curves to the top of the fuel tank, on the inside.

        i just installed a perry pump and the instructions say not to use muffler pressure to the tank. my question is, how do i vent the tank properly so i don't create a siphon from the vent line?
