I have a 2019 450 that will not drain the water separator tank to empty so that the filter / separator can be replaced. When I open the water drain fuel drains continuously. I've tried with a 1/4 tank of fuel and a full tank of fuel but no matter how long the water drain valve is open fuel continues to flow, drained 7 gallons this AM before giving up.
I've tried with the fuel cap open / closed. I've tried by changing the under hood filter first and not. I've tried breaking the seal on the separator but fuel flow just increases and runs out from the sealing area.
We have 4 other 450s, a 550 and a 350 with this same fuel setup and none of the others do this.
Thoughts?
