    What hoses do you all have on your manifold? I got some JB 72" ones with the 6" extra hose past the ball valve. They were too looong.
    So I went to the local "supply house" for some YJ low loss hoses. All they had were 36".
    I can't get this right!

    Oh geez. I can only imagine who that "local supply house" was.

    They don't have anything good there.

    I prefer 48" or 60" hoses with the ball valve and 6" hose section.

    Does your manifold have all 3/8" ports?

    Nope but it still pulls a vacuum faster.

    When you hook up with that style do you purge out the 6" part first? Or am I over thinking this.

    I normally keep some gas in the manifold to purge out the 6" section.

    5 ft on my digicool for ac and walkins.
    I have 3 or 4 ft on my yj analog manifold for small refrigeration. I have a few other manifolds that have 4 or 5 ft hoses. I use all ball valve now. I had the low loss ends, but wasn't a fan.

    So 3/8 hose with 1/4" ends, except for the 3/8 fitting to the vacuum pump

    This. Before I take my gauges in, I purge them with whatever flavor is in the equip.

    That's what I've done, just didn't know if I was the only one that worried about it.

    The ball valve style can spray more liquid During hookup depending on the Schroeder depth

    I once bought some really cheap imported hoses.

    I would advise against those.

    I especially do not like the slim JB style low loss hoses. They are harder to turn and don't work so great. Jmho
