Does overfilling the fuel tank cause any damage (ie: problems with the fuel return system, etc.)? Diesel foams so much that I slow the fill rate way down when I think I'm getting near full to keep it from spewing out. Filling slow keeps the foaming down, but I've accidentally filled it nearly to the top of the neck a few times. Have I damaged anything?

Thanks in advance.

No. You be fine... except for that stain running down the bedside.

Thanks Max!
