Threw this together out of an air tank, tire filler
some spare parts and a 30 psi gauge
quick disconnects works great!

I have a simpler one, frame mount bicycle pump, with a pressure test guage and a couple adapters from the plumbing supply. Pump mounts to the guage at the schrader valve, tubing goes to the pulse fitting on the cases. A few pumps and you have it. I also use a second very accurate Holley fuel pressure guage attached to some tubing and use it on the return line to verify my findings.

I already had the air tank, tire filler etc for servicing my 4 vehicles and two trailers + bike, balls, etc.
threw together the T, gauge and hose connector out of spare parts at work.
the tire inflater is great in that it gives you lots of control!

Really? :dunno:

I know it takes half a pump on the Mikuni tester to go one or two psi, so I don't know how you can be very accurate with a compressor. :dunno:

I would have to agree with Matt, you need to go very slowly when getting near target psi.

well that is the slick part.
it isnt connected to a compressor; it is connected to an air tank.
fill the tank to just 25 or 30 psi, depending on your target popoff
and the fingertip control works like a champ
 
i have an air compressor-driven popoff tester.

the trick is to turn the regulator down to about 50 psi and have a valve before the guage. mine also has a small twist valve to let air escape until you get the right (slow) flow of air. you can get the pressure to smoothly climb at about 2 PSI per second. its way more accurate than a handheld pump thats shaking all over while youre pumping.

i also have a mikuni guage which is ideal for checking popoff w/o the use of a compressor.
