Nat,
<br>I think it's head pressure. Not only do they ALL do it, they do it
when it's really cold out, when it's really hot out and everywhere in between.
When the level of the fuel in the tank passes the level of the inlet tube(pick-up
line), the pressure change from head pressure to now having to lift that
column of fuel up the line, even though extremely slight, leans stuff out
slightly and is even apparent in pressurized systems. I could easily be
incorrect on this conclusion, but that's my take on what I think is happening.
