Kevin,

The port is pressed in. I removed mine, tapped and = plugged. It=20 would be easer just to weld it shut or use it as Tracy recommended. I = think the=20 port would be very helpful on a tail dragger.

Us a -6 or = so line from=20 bottom port on exp. tank to the pump outlet or highest point in cooling=20 system

The bottom of my expansion tank is plumbed to the = pump=20 inlet. Did I do something wrong?

Bobby
