Sounds like the vent line is too low and they know it.
As another suggested fill slow and see what happens.
On my bayliner I always filled it w/ the pump set on the lowest notch. If
you filled fast, it would splash back out and all over everything before the
pump could kick off.

Same thing here with a Bombardier Utopia 185. If I know the 40 gallon tank
is half full, I'll leave it up there for about 16 gallons, then back down
to the first notch.
