I need to find out what my hpop pressure is. I have a obd2 snap on scan tool but cant find the guage on their so i was gunna just buy a real guage and hook it up. Where do you hook it to? And what ones are good and easy hookups

 

You will need a gauge that can take up to 4000psi... You can hook it to any one of the free ports on the heads...




They are AN4 fittings...


The one in Green would be the easiest to tap for a gauge...

 

On your Snap one tool it would probably be under Injection Control Pressure (ICP)

But anyway what Joe said will work if you want to go manual gauge.
