OK... now.. what about for fittings/aluminum lines that appear NOT to be 
subjected to flex loads but still on the engine. For instance, running 
from a rigidly mounted PSRU to the engine block..

This should be a pic of a rotary with Tracy's PSRU on it, from Bruce's 
webpage. Can I run AL tubing to AL fittings from an AL block to the AL 
PSRU or again, should it be steel for safety (or convention's ) sake. 
I'm really not HUNG UP on AL.. i just dont want to have to buy ANY part 
more than once...and I'm getting ready to go buy parts.
