I installed a length of hose that loops over my LPG tank and I zip tied it off. I then placed a PVC valve at the bottom so I can drain any residual water out. I fill the tank until I get water climbing the loop or even if it spills out, once I turn the water off it doesn't siphon.
Before even after it stopped draining I could see water hitting the ground where turning or stopping would cause the siphon to start again and dump gallons on the ground. Now, I don't lose a drop on the road.
I even asked the dealer to apply the FR repair I've heard about but they said what I did was much more effective and they might look into doing similar to others with the issue.
