I would recommend the below option. I had a gauge pod and 3 gauges. It cost me like $800. I gave up once I bought the fuel pressure gauge. Too much work.

I scrapped it and went with this instead and so glad I did. For $<400 I have almost any gauge you can think of at my fingertips when I want. It also has 1/4 mile timer and many others including 0-60.

I know it's not the answer you requested but wanted to share how cool these Android decks are with ob2

5/16. The car doesn’t have a low pressure sensor so you’ll only be able to monitor the high side fuel pressure sensor with the app on the radio. Low side you’re better off just T ing into the fuel line/rail and put a mechanical one there for fault tracing use

oh wait would i be able to check fuel pressure before the regulator? or does it have to be after the regulator?
if after the regulator what is the best method to hook up a guage?

We have no regulator. Our fuel pump has a duty cycle and it goes up and down depending on load iirc. If you have a mechanical gauge like the auto meter ones that run into the cabin then it should work. But if you’re just planning on putting a gauge up to it right there I don’t see what the advantage would be as you can’t see it when you’re driving.
