Rob,

Most of the time, I can use the high setting. I understand when the
gas station puts new filters in the lines, one gets a faster flow,
dirty filters flow is slower.

I have experienced no need to stop and burp.

I do get a splash out of the filler if I let get full at the high
setting. I usually calculate how much gas it take to get 10 MPG and
when that number comes up, I go to the slow setting. This avoids
splash back. My 13,500 lb coach gets a steady 8 MPG.

Chuck
