Follow up from my post #20. Loaded my deuce dump for a firewood delivery and she prompty died when reaching just shy of red line rpm's. Complete loss of power, sputtered and stalled. Bled the fuel system, she limp down the road aboat two miles. Repeated the process twice more before getting her home and unloaded.
Went through the fuel sytem from front to back. Pumped all wmo and diesle mix out of tank, dropped tank and cleaned (few rust particles nothing more), checked fuse (fine), blew out remaining wmo from fuel lines, replaced filters again, lastly replaced pick-up hose and checked all electrical connections on fuel pump ...just to be sure.
Bled fuel sytem and truck fired up. Reloaded firewood and made a 30 mile round trip delivery. The truck regained lost power and performed as before the introduction of wmo. The only noticeable remaining problem is the engine did begin "hunting for idle" when parked. After two more similar deliveries the "hunting for idle" is barely noticable. I suspected some remaining air is in the sytem.
My truck with FDC engaged did not like wmo at all. There may have been a very small amount of water in the alternative fuel but I doubt it. The oil came from a friends garage and he had clear instructions not to give any wmo were it could have been contaminated from a blown head gasket etc.. I filtered the oil down to one micron and it sat for months.
The truck does have the yellow stickers on fuel cans "saying diesle fuel only."
My plan...was to ignore these stickers based on my sesrches here on site as many burn wmo with the FDC engaged with no problems. For me and mine ...that turned out to be a very bad idea!
