water in tank problem

[Fazerider]

If your cap seal is in good condition, it not only stops fuel and fuel vapour coming out, it stops water getting in.


don't worry about water in the fuel, just make sure the drainage channel isn't blocked.

My Fazer was almost always parked under cover, the drain was kept clear, and yet the tank rusted through from the inside. I can't blame ethanol in fuel either as regular use meant the petrol was always fresh.
Inspection is easy nowadays though, a USB endoscope only costs a few pounds.
