Hi Mark,

Makes me feel better now that I understand you are returning fuel to the
tank.

What pumps are you running because the Walbro pumps seem to reprime with
or without air in the line at least under all conditions I run into.
Seems like Al G  said he has similar experience.

My pumps are about 5 feet of #6 line from the tank and maybe 12 inches
higher than the tank.
