That would make perfect sense.  The air would compress, thus absorbing the
pulse.

Joe,
It's my understanding that the same principle applies when we are talking
about air in the lines after the injector pump. That's why you need to bleed
the lines, the air bubble absorbs the pulse and doesn't move down the line,
as one would expect.

I haven't had it happen to me, but I am wondering: If I'd carry a few
feet of refrigeration grade soft copper tubing (for bendability),
and the necessary cut and flare kit complete with a selection of
fittings (or compression fittings), could I not make at least a
temporary repair? I recall from my refrigeration days that soft
copper tubing can stand a few thousand pounds of pressure. Price of
material and tools should not be exorbitant and could of course also
come in handy for repairs to reefers etc.
