James,

Too many years of driving diesel, where you burp the expansion tank (not as essential as on a gasser) to get another gallon or two.

I have now replaced the flex fuel/vent lines on the expansion tanks and life is better.

There's very little vertical height between the top of the gas tank in our beloved vans and the evaporation control tanks and gear - I asssume that's why the warning.  Certainly on our '91 if I top off the tank (only did it once) I get strong gas fumes, but if I stop when the pump kicks out, then the fumes don't happen (except on really hot days, if I park soon after fueling).

Things are well mechanically thus far - the only issue is the lines to the overflow tanks need to be replaced. I bought some line in Calgary and will attend to it, the first chance I get. In the interim, you stop filling when the pump kicks out.
