   I suspect a lot of us have "contamination" of tiny aluminum particles in
our lines.  I blew out my newly made lines with compressed air.  Then, with
the gas lines, I pumped gasoline through the system, collecting it at the
front of the engine, running it through a coffee filter.  In bright sunlight
I could still see tiny sparkles of aluminum (presumably) on the filter.  I'd
be interested in what others might find with that exercise.  At any rate, it
would be a good thing to do with your gas lines and perhaps the hydraulic
lines too, clearing them out afterwards.
