Jeff,

You may wish to consider Parker Parflex nylon hose. It is available in
several wall thickness at 1/4 inch OD. The hose is UV stabilized so there
is little worry about it becoming brittle after a few years of exposure to
light (you could always paint over it). Minimum purchase lengths for most
1/4 hose is 100 feet. If you buy the 0.035 inch wall hose (1000 psi burst),
that will cost you about $30 for the 100 foot spool.

Parker's catalog for tubing is available on-line at this address:
http://www.parker.com/parflex/images/4660-cd/4660d.pdf

Go to the thermoplastic tubing section and from there select nylon tubing.
Burst pressures range from 1000 to 2000 psi for 1/4 OD tubing depending on
wall thickness.

For fittings, Parker sells a fitting called Compress-Align that works with
this style tubing and has a high use pressure. Info on these are available
on-line at this address:

Whatever you decide, best of luck,
Charlie Smith
