Came in about an hour ago. Replaced all fuel filters. She fired up and ran as before the introduction of wmo (no stalling/coughing or loss of power...yet) The filters did not look clogged, it is more likley that moisture was in the wmo. I had filtered it but had not cooked it in the 55 gallon drum via barrel band heater to disipate possible moisture.
When I purchased the truck I did in fact clean the tank, intake screens and checked all electrical connects. There was no algae contamination. This truck was not a GL purchase rather from a private seller. Dog Head thank you for your post, that same article I did in fact uncover during my search's on the site . That article helped me determined that my FDC was engaged. The disengageing of the FDC may be my next project, not that I find any contamination (yet) in the crankcase.
I know that many burn alternative fuels in their trucks, I am not convinced this is the best day to day fuel source for our machines. I am not knocking others. Yes it will work, and was designed to do so when needed in wartime. It certainley is a cost saving alternative to pulling up to the pump. Like some, I use my truck to put bread on the table. Sometimes we look for cost saving alternatives. Therfore, I began filtering as the wmo oil was free.
Just my two cents.
