Melvin, I clean the bowl once a year, but my float does not budge indicating that there is little or no water in my fuel. If yours is routinely creeping up, you might want to review all the possible sources of water in your fuel. Hints forreducing the problem include using a Mr Funnel, and keeping fuel tank in tractor topped up. It is worth doing because the high pressure pump in the common rail tractors is reported to be fussy about contaminated fuel..With that much water you will likely grow algae somewhere. An algicide might be a good idea.
