After making some mistakes on my first whip (seen here) like using low pressure fittings I decided it was about time I did the job up right. I also wanted to include a few upgrades to the system to make it even more versatile than the original model.

Changes include:

1) Digital gauge

2) Fill whip extension for long reaches or in the future a second bottle tied into the system (the supply gauge can now function as a basic manifold for a second supply bottle, with it's own needle valve)

3) .025" orifice to reduce the flow even further when additional precision (via slow fill) is desired.
