Hi Jon, I had a period when my 900 used to dump fuel as well...it all went away strangely after I changed the one way valve on top of the tank (with the hose that runs through the top of the tree. Otherwise sadly, it looks like time to explore inside the tank - I need to do this over winter too as its time for a fuel filter change I think....something you might consider doing if you are going inside the tank. good luck - frank |
