the fuel press reg. is ok, it sees both boost and vacuum, the line to the bov should work too. I had an autometer guage and it wouldn't show boost over 10 psi, had to send it back for a new one. You can check for leaks but if your boost is showing normal numbers then I would think about sending it back to them.

 

First Pic- you can see I tap the line there.. but not from the post on the Defi gauge install?? So do you think I just have a leak.. or should i tap the other line???

 

just sent back a gauge to Jeg's today.. I have auto Meter Cobalt Electronic... I see boost but no vacuum and sometimes 1 psi boost..

 

That line will work. Is electronic sender wired up correctly. I have a manual guage so there is less to the install.

 

actually i think you should use the line before the fuel pressure solenoid coming directly off the intake mani.

 

its just plug n play.. don't have to wire nothing up but two 12 volt power and ground

 

install it here !
