Yeah, that smaller nipple restricts the flow. Larger pope/hose on the other
side will only give you a split second more volume.
The 1/2" on the other side will not add but it will certainly help to not be
as restrictive as 1/4" pipe would be.


Correct - the effect depending on how much of the larger diameter pipe
is downstream of the restriction. The more pipe volume downstream of
the restriction the larger the effective tankage.

A quarter inch orifice in the line will restrict the flow more than if
the orifice wasn't there, but nowhere near as much as if the entire
line were the diameter of the orifice. The larger the pipe, the less
pressure drop per foot for a given flow rate - or - the greater the
flow rate for a given pressure drop. And, ignoring start/stop
transients, steady state performance is independent of where in the
line the restriction/orifice is located.
