Dave,
I have had new lines made by a local NAPA store with a machine shop.  I
have also had them made up at a shop that normally does hydraulic hoses
for farm tractors and industry.  All of the new hoses you can get now
are barrier hoses.

You might want to check your schrader valves (bicycle stem looking
valves where you charge the sytem).  They can stick open and leak or not
seal properly.  You can just spray a little soapy water on them and see
if they leak (or do as Gomer Pyle suggests and spit on them and see if
they bubble:-).  If they bubble then they need to be replaced.  If not
then you can blow the water out of them with some compressed air.

Hope this helps,
Ken Wilford
