2009 Kubota RTV 900, 2009 Kubota B26 TLB & 2010 model LS P7010
I do use farm diesel for my tractors. My LS has a water in the fuel filter sensor and since 2010 when I bought it I have never had any issue with condensate in any of my diesel vehicles. RTV and B26 both have over 300 hours on the same fuel filters and they are all still clear (actually red and clear) in the see thru filter bowls. I keep my tank indoors where temperature fluctuations are not as radical as outdoor tanks and no rain or other precipitation can get to it. I also have my pump suction a couple inches off the bottom of the tank + the fuel goes thru a 10micron filter when being pumped so it is clean from the distributor when it goes into my tank, clean when it comes out and goes into my equipment. I trust the distributor to have clean fuel more so than a local service station that may never check their tanks or dump the water from them.
