Diesel Smell

[Gregory OConnor]

Jim, I don't have a coach that new, don't have any friends with that
kinda money but. the problem must be ;tank vent or ;injector line
crack; or fuel supply to injector pump leak.

If after being unstarted for several days the smell is still present,
it is most likley fuel tank vent location. I would locate the tank
vent and raise it. Call AZ bus sales in Colton CA.

You can dust the engine with talc, and run it, then look for the
wetspot. ( Mike, I will refraim) That will show possible leaks in the
high pressure fuel rack that is so fine it makes the airfuel mix
dangerous.

You may be able to turn the key on and listen to see if the pickup pump
keeps cycling on and off. that will show a leak in a line from the
tank to the high pressure injector pump.

the other leak may be a return line from the injector rack to the
tank. to find this you would have to disconnect line at rack and tank,
plug one end and pressurize the other.

Hope it helps
bring your bus to the SW Rally next week, everyone is parking downwind
of me also.
