pressure guage weirdness


Donating Member
Just installed my new Dynotune digital pressure gauge. The sending unit is mounted right at the base of the solenoid. I just got a fresh tank filled today and bolted it on - guage says around 1200 psi. WHOA! I thought a fresh bottle should only have around 900 or so?

Is this normal or possibly a calibration issue? Thanks in advance guys - sorry for the continued newb questions.

Forgive the cell phone pic.

nice !

if the bottle is over full and warm,thats normal

i have had them in the 1400's

as soon as you hit it ( if you don't stick the solinoid ) the pressure will drop  down to normal
This pressure gauge is pretty cool - N20 guys might want to look into this.

Better, but still not that good, picture.
