Diesel Deckplate ERUPTION
I have the same problem but not as bad. I also don''t know why this happens but I have a solution. I now pump the fuel into 5 gallon carry-on jugs and then siphon the fuel into the tank. The bubble-over never happens when fueling this way.
I suspect the bubble-over has something to do with the pumping mechanism of the diesel pump since it doesn''t happen when siphoning. It also doesn''t happen when filling the jug, probably because the opening is quite large.
This would be arduous for tanks the size of yours but, never-the-less, a solution. You might be able to simultaneously pump diesel into the jug and siphon it into the tank while at the fueling station. Good luck.
