Thanks for this thread - I've been stewing over how to rig the fuel system.
Questions
(some of these may be answered when I receive the builder's manual...):
Standard size Andair gascolator or the new mini size? Assume Rotax 914 max
capacity.
What connectors? -6 AN, or NPT?
Aluminum is the standard for factory aircraft - what are the DISadvantages
of aluminum fuel line over nylon or other plastic lines
Is a duplex fuel valve necessary or can I get away with a single? I love
the Andair valve, but $420?
thanks,
shaun
