My guys came with another explanation for my grief, they claim since that skid steer is stored in a cold building there's water frozen at the bottom of the tank and after running a while the fuel gets warmed up and melts the ice which in turn gets sucked into the filters and in cold weather cools enough to gell the filters. Now this might be the case and there is a chunk of ice in the bottom of the tank but for the amount of problems we have been having it has to be a large amount of ice to cause the problem which makes me wonder how condensation could be the culprit, that is usually only a small amount per tank and we are changing the filters about 5 times per tank and have done so for about four tanks now, we just take the filters off and shake them out and let them sit for a few days upside down on the heated cement floor in my office and dry out and then switch them out again. I know its not ideal but at 30 bucks a filter and the nightmare the tank is to get out I figured we'll get it cleaned out eventually and then toss the filters and put on new again and start over, every time the filters gell the sediment bowl has ice in it and we knock that out as well and fire it up again and run it unitl the next time it acts up. From the sediment bowl alone we have to have dumped out pints worth of water thats frozen, its way more than any condensation could put in it. We don't yet know how that much water has gotten into the system but its only on one machine and all things get fuel out of one large barrel so its not fuel contamination in there, we are wondering if someone dumped water deliberatly into the machines tank somehow but thats only speculation.
I need to put it inside and let it melt the ice out and pump the tank out but right now my heated shops not done yet and up and working so we'll either get it all eventually or else spring will make it here first.
Another problem we've had is overtreating fuel, we would buy fuel that had the additive already in and to eliminate problems we would add some more and things would get worse, we were finally told that the additives we added and those already in were not compatible and after you add about so much it works the opposite and makes fuel thick again. I don't know how much truth there was to it but after we quit adding more we didn't have any more problems. The other thing we have done over the years it to run straight number one in the winter months, we got tired of the additives and blended fuel and gelled filters and all that and with the exception of this skid steer its been years since we've had major problems in the winter with machines, trucks thats a whole different story and a few years ago we went with straight 1 on road in those as well and thats solved those problems too. I've heard all the data of less power and lower fuel economy but when its -30 below and your machine sputters and quits in the middle of nowhere, fuel economy isn't the first thing that comes to my mind.
