In Tok at Three Bears fuel station pump #7 I bought 21. 0 gals of diesel. Truck ran lopey died twice when put in gear but restarted. I thought I had bought some old #1 and drove on to Glennallen about 130 miles then topped off with 10. 0 gallons then to Palmer added another 10. 0 when I got home to Anchorage I pulled a sample. It smelled of gas so I changed filter and added some oil to the new full tank of 6. 0 diesel in Anchorage. Truck runs fine but lift pump might be dead. My wife verified it was the diesel pump as does the reciept. I wonder how much gas was in the 21 gals ? It could not been pure gas as I would not have made it 130 miles. BEWARE
