Strange Diesel Fuel Fault

Went for a 900k jaunt over the weekend and was almost home with one tank reading empty and the other on 1/4 when suddenly lost power. Whilst slowing from 100kph I quickly switched to the almost empty tank and just managed to get power back before coming to a stop. Worried about fully draining that tank so a few minutes later tried the 1/4 full one again with same result of power loss. Back to the "empty" tank and just made it up my driveway coughing and spluttering with the engine failing completely as we pulled into the carport! Allah surely was sitting on my shoulder!

Now the interesting thing is that in accordance with thread 76538 I had, for the first time, added 500ml of two-stroke oil to the tank that gave the trouble. Not saying that it caused the problem but its hard not to be suspicious.

Anyway, I'll start to examine the system tomorrow. Maybe a dodgy tank-selection solenoid valve. Fair dinkum, if it is I may consider ripping them out and replacing them with manual valves for tank selection. After-all, I can't afford to have some stupid device such as a solenoid valve stuff up in the middle of nowhere and anyway, I don't need to select tanks whilst actually driving.

By the way, I had put the two-stroke into only one tank and had changed supply a couple of times to observe any performance difference. There was none that I could detect, certainly no difference in engine noise or response. So endeth the experiment!
