I think I have gotten used to having some fuel in the low point of the vent lines. Now I don't fill my tanks as much so that the vent lines only bleed air pressure (or vapor pressure). I am just wondering why they are not vented down to allow fuel to escape instead of block the vent when the fuel heats.
My understanding is that the pressure in the tank is not able to to force the fuel in the line up over the fuse entry point ( I think that is the high point).
A second question is what happens to the fuel that might make it into the vent line? It doesn't seem to be able to blow back into the tank. Is the use of the fuel in the tank creating some vacuum that eventually suck the line clean again?
Thanks!
