Fitting size does matter, a lot in fact, regardless of which side of the regulator it's located. I ran into this recently with a cheap gun regulator(diaphragm type) that, although it regulated the pressure just fine, it has a bore of quite a bit less than 1/4" at the smallest point and will simply not flow enough volume. The fittings MUST be big enough to flow what the gun requires.
