GrkGuy, looks real good, but just seems a bit complicated. Why didn't you just get the pressure tester from HB's website? Would have saved you all the trouble with fittings, soldering, etc. and shipping is $7 i believe.

I agree about the plugs though, they will be different depending on your setup so everyone should find what works best. I just took my carb and my exhaust flange to home depot and had plugs for both within 15 min.
