Ok cool thanks.
How often should u drain it if u don't have the light on? Every couple months?
Ive had to do that once in 265k miles....Id recommend you not make a habit of buying crappy fuel/water emulsions. Only reason Id say crack the valve twice a year is that at 250k I removed the fuel bowl to fix a leak and the drain valve wouldnt work because their was so much dirt in the bottom of the bowl. Might wanna keep it cleared out for that reason alone. I was putting 30k a year on mine so lots of fuel going through that bowl.
As for mileage and changing the filter, I dont know. Ive never had one plug. Had one instance where my fuel gelled. Althought the gelling took place in my 03 sd cc/sb f350 7.3. I put fuel in it from a bp truckstop and about half hour down the road my truck sputtered and died. I knew why!!:doh: I took the filter out and heated the bowl with a mapp torch then put some solvent I had in the toolbox in the tank(I dont recommend doing that) to help liquify the fuel. I dont know which part worked but I was back on the road. I stopped in the next town and put PS 9-1-1 in the tank and fuel bowl. Never bought fuel there again and always carry additive in any diesel I own.
My point? Change the filter two or three times a year and buy fuel at a place that sells GOOD diesel. How do you figure that out? Ask around, keep track of your mileage(indicator of poor fuel source), and figure out what your particular truck likes. My truck runs fine but uses A LOT more fuel when I run bio-diesel.
Good luck!
