My problem is similar but I bet it's related.  Mine consistently throws up 
at the end of filling the tank.  This can be avoided if I estimate the 
amount of fuel needed and manually reduce to the minimum gas delivery rate 
for the last gallon or so.  I only have it shut off early maybe 5% of the 
time.  I think the diameter of the tube is the cause.
