Subject: Re: [LML] vacuum hose

Column,
Why not just use nylon tubing - clear in color, flexible, pennies per ft., a=
vailable at hardware stores in various diameters.  Is your pump in the bucke=
t with the pressure dump valve?  If so you couldn't need more than 10" of ho=
se. =20

Tygon tubing should work as well.
