    Judymw asked the specific question. There are replies by more
    knowlegable people than me about the general, but they didn't quite
    hit the specific. We went natural gas for most things, but I wanted
    to use my big torch, which has FB arrestors built in. The natural gas
    at line pressure doesn't have enough pressure to go through them,
    into the tip. In other words, the torch won't work - won't even
    light. It requires a minimum pressure, which gas out of the line
    doesn't have, to use them. By the manuf. statements here, the booster
    does raise the pressure enough. But gas from the line won't get
    through the arrestor by itself without a boost. At least not mine. We
    just use NG on a daily basis, and have an oxy acetyline for casting,
    brazing, welding and the like.
