You can easily test that one,take the return hose off and place it directly
in plastic bottle/can ( 2 or 3 quarts capacity minimum and extra guy behind a wheel) if looping is still around go for gold rack dumper...or higher idle rpm's

Only if there is accumulated fuel in the collection container from the return line. If there is not do the relatively minor things to get the return flowing.
Actually a good test to see if the idle is impacted on cars with no cigar hose present. No return flow could also be construed as having no cigar hose effectively dampening spikes..
