Can anyone enlighten me on what the fuel return line flow rate should be--or rather, what it will look like. I checked the flow with an endoscope, and observed the return flow was not constant--the fuel level in the return line bobbed up and down, overflowing and putting out a drop or two of fuel every five seconds. I vaguely recall observing this a while back, and in was a constant, though slow flow.
