Alu tubing for fuel

[Fergus Kyle <VE3LVO@rac.ca>]

Brian:
" Also, how frequently does aluminum tubing need to
be clamped?  Every foot?"

            I must suppose it's particular to each country, although can't
think why - the alum alloy doesn't know where it is........
            In Canada, and some others, it's every 16 inches which is what I
have done.
