Default RE: Burp tank-what is it?

There is a method of filling B-less tanks that uses a burp tank. You use three lines like normal (exhaust pressure, fuel to carb, and filler). When fueling, the plane is held vertically with the fuel to carb line leading into a regular tank (burp tank) that is just loose and used while fueling. You then fuel it up using the filler line and watch the line heading into the burp tank until there are no bubbles coming thru. Apply hemostats to the ftc line and reconnect.
Can't really comment on the benifiet of this method, I just seen it done.
