Why you diagnosing houndog. Good call!
Few theories:
1. Low level gas tanks cause condensation in a higher humidity climate = Keep tank full.
2. High level gas ~ After you filled it, sitting for months of drops up top = Water is heavier than gas/oil.
3. Hot air rises, you go home after a ride with low gas, I'll gas next time out. That hot air is a good adder to the wet, damp cave that take is in. Dripping water off the top of that cave.
4. Water accumulates where it is, remember, heavier than gas; settles after all those half filled tank runs.
5. Water level is now suckable at said whatever the suck level is, it is now sucking in water.
6. Water flood back when was the last time you filled up is stay away from that place is the other theory. Where is their separation filter or whatever they use for rain down the holding tanks.
So goes one theory, where you live, how much [level] you leave on the tank walls... Foothe note: I top off my tank so as no condensation down the road [if] I park it for awhile; I covered my ass. If you hear her sing a purge in the garage? Probably too low a gas level. Has lots of air to expand and now load that rubber party noise maker.
