If so how and where did you hook it up? any pics of your install?
Wondering the best way of doing it myself, either I can get a quick release braided s/s pipe made up with a quick release t-piece so I can plug in and do measurements as and when. Or have a boss tapped into the fuel rail and have a guage in the car..
Any suggestions welcome

 

The SX regulator has 1 spare outlet we use that to either run a small sight gague under the engine or plumb in a sender to send the reading upto the dash.

For a quick reading or setting up we have a schrader valve on 2 bits of pipe, this gets placed in line (feed) and a normal tyre pressure gague pushed onto it gives you a close enough initial set-up reading.
