6V92T no power black smoke

Troy brought the bus back here yesterday. Him and his family joined us for Turkey Day - And a great day it was!!

He got the old gal all welded up. Changed the secondary filter and flew down to our place (about 10 miles) no problem. Guess it was the filters (again Bryce!). There must be some creepy crawlies living in the tank. We changed both filters back in Missouri and now it needed them changed again? WTH.

Also welded up the exhaust. It had several leaks ahead of the turbo so that might have helped things out as well.

The project progresses. Hes got all the new plywood stacked in my shed and finished gutting all the interior today. A neighbor has construction demolition dumpsters so we hauled all the carpet; ceiling panels and other miscellaneous crap over there today (and drank a couple beers)

My MCI is starting to feel neglected.

Fred,

There is a high probability that the old diesel was growing algae in the tank from just sitting around. Filling the tank and then driving to Minnesota took what was a sedentary algae bloom and put it into suspension so it could be sucked into your fuel supply system. The chances are very high you will be replacing fuel filters about every 1,000 miles until the algae is all gone and you are back to just plain diesel. Carry a couple pairs of spare filters (primary and secondary) so the change is easily made on the road. Don't forget to stow away some diesel in a 5 gallon (that is as small as I could find a yellow plastic diesel can) can so you can fill the new filters and avoid having to prime the fuel system.

I had a similar experience this past summer on a trip from NC to OKC and back. I'm on my second set of fuel filters now. Oh yeah, change both filters at the same time, primary and secondary. I also would not let the Eagle stay on a perch this winter. You need to find time to get it out and run down the road 100+ miles at a time or the remaining algae will just grow denser and be more headaches come springtime in Minnesota.

Fred, I would get some biocide in the tank.  One source is:  http://www.powerservice.com/bk/

I would again suggest the Fuel Pro type filter.  That way you can keep an eye on the situation and change the filter before the bus gets into a fuel starvation situation.  I also think the process of changing the filter is much easier and less messy and it is almost impossible to lose the prime.

Do you guys think that the twenty below zero weather here this winter will help any?
Seriously, I'm familiar and have had good success with Power Service Products. That sounds like a good plan.

I'm surprised that plugged filters would cause black smoke? I don't quite get it.

Fred, 2 strokes are a different animal it will amaze you how much white smoke some engines will emit when they lose the prime but the black smoke from the plugged filters are usually from a missing engine.  
The way I clean fuel is by using a house type water filter about 20 bucks at Lowe's or HD take the pickup hose lose from the fuel filter connect the line to the filter and a pump (I use a old  RV 12v water pump) drop a hose back into the tank for return then after pumping for a few hrs and when no more gunk is present in the filter add the sea foam.
I know RV water pumps are not approved for pumping fuel but they are plastic not any danger of fire and they work good LOL what else is a old RV water pump good for.
If you read the instructions for the bio crap it calls for filtering before adding it to the fuel that way they know it will work
good luck
