First off let me say that we are traveling and do not have access to many of the things back at Base Camp.
We have just recently done over 400 miles, about 275 of it on dirt tracks, and have been collecting and using WMO as fuel. About 30 miles after one of our "fill ups" the 109 started surging. I've had this happen once before on my m35, changed the primary and was back in action. This time I did a quick filter change out on the side of the road, she fired up . . . and off we went. Maybe, another 20-30 miles and she was doing it again. Did another quick change (we're carrying a few filters of each type that we need . . . and I am getting to be an expert on how to change them), it didn't help! And, the filter looked pretty clean.
I've now also changed both the secondary and the final.
I've also read every thread that I could find about such problems.
What I find odd is not only that Elise's 109 is doing it but not my m35 (We have both trucks and a 105 w/ us), but that if we let the truck sit (some times for only 10 mins) it will fire up and run great. 10, or 20 miles later it starts losing power . . . then surging . . . then finely it will not even idle. She did get oil from a drum that I did not, so I tend to think that it was something that we picked up from that drum. If it's not the filters what could it be? I did run a half gal of oil into a container while I was picking it up and there has been no water separation over the last week. The in-tank pump works. I don't know the pressure but it runs out the draincocks and bleeder like normal. Tomorrow I'll try draining the tank to see if I can find something in there . . . I don't know what else to do check.
I've been filtering the oil through a basket strainer when pick-up pumping and multiple paint strainers on the way into the tank. I've just changed our pump from air power to 24v and added a fuel/water separator w/ spin on filters that have a draincock. Tomorrow should be the first test of this "New & Improved" fuel processing trailer.
But in the mean time what is making the "She Beast" surge and lose power after 20 miles?

And, of course, we have a deadline to get back so that Elise can take some classes that she's signed up (and payed) for.
