it does not need a check valve.

Yeah... I have no idea what that poster was thinking... it had nothing to
do with gauging.


Just my observation that without a check valve, he is using the pump
head discharge valves as a check valve.

Ig... If you need to plumb the gauge in a pulsing line to make it more
accessible or visible, they sell "gauge line snubbers" designed to do
exactly what you want -- take the pump pulses out of the stream before they
reach the gauge.
