I started my bus today for the first time in a week. it galloped for a while like it usualy does when it's cold then smoothed out. then it started vibrating and quit. I still have fuel about 40 gals. It's been cold down in the low teens. any ideas where to look first. It acts like its out of fuel. does deisel gel in that type of weather? I need to take it on a road trip fri. |

#2 diesel will "cloud" at about 35 degrees farenheit... clouding is the parrafin showing up.....that's present in all diesel.... you may have a lot of water in the water separator... water freezes at 32...check your filters... |

Man..... "It's been cold down in the low teens. - It acts like
its out of fuel. does deisel gel in that type of weather?"
Yeah. Sounds like jelled fuel. Ya' got a space heater and a
lot of time? And..... a nice heat gun to aim at the filters?
With our old Mercedes, Volkswagon(s), and Peugot(s), we
added some of the great gas line anti-freeze... and a gallon
or two of gas to the diesel fuel. Maybe someone here can
say if that's OK to do with a 2 stroke? I don't see why not...
But hey.. |

Sounds like it ran out of fuel. There's probably an air leak in the line someplace and your fuel drained back to the tank while sitting.
Reprime it and try again. |

DON'T add gas. To prevent gelling, add K-1 kerosene--I usually use about a 10-15% mix at the most. |

I have never had my bus in cold climes so do not know what contribution that could be making. I did once have a similar starting problem that turned out to be a cracked fuel line that allowed air to be sucked in. |

----------------------------------------------------------
Q: Should an additive be used in the fuel to keep it from clogging the fuel system?
Below 15 degrees F, wax crystals begin to form in diesel fuel. These
crystals form a gell that will clog the fuel filter or fuel lines
and stop the engine as the temperature drops toward 0 F. Any good
"winter fuel conditioner" for diesel fuel will keep the fuel moving
to at least -20 degrees. Follow the instructions on the bottle!
Q: How can I tell when the fuel begins to gell?
The first hint is often an unstable idle. The idle speed may
increase to 1000 rpm or more and fluctuate slowly. Next the engine
will begin to lose power. Within a few minutes the engine will quit
and not restart or will only restart briefly.
Q: What can I do if the fuel has already gelled due to the cold?
The time proven remedy is to add a gallon of kerosene for each 10 to
20 gallons of fuel to the tank, then allow it to sit long enough for
the kerosene to diffuse into the fuel. In weather below -20 degrees F,
one gallon of kerosene for 10 gallons of fuel will keep things
moving, but fuel economy will be reduced. Kerosene now has red dye
which a DOT inspector will assume is off-road diesel. Be prepared
for a hassle if you are checked. Apply heat to the fuel filter to
break up the wax.
------------------------------------------------------------
With only 40gl in the tank and temps in the teens... It should be real
safe to assume the fuel's jelled. |

I have the 8V-71 as well... I'm lucky I guess. I did all the fabrication on my bus in Northern Minnesota... during the winter. The temperatures were below zero most of the winter. I would heat the garage while I was there working on the bus, but most of the time it sat in the cold. It always started and ran perfectly, even the times I started it in the cold to back it out. Kansas, the previous april, was the last place i had fueled it. I doubt there was any additives in the fuel.
After reading this thread, I am amazed that I had no trouble. I had some trouble with frozen water in the air lines, a learning experience, but she ran real good. |
