1. Looking to put a fuel pressure guage in my 92. What are you guys running, and if it is in the cab, what type of isolator are you using (assuming your using a mechanical gauge)?

2. What should the fuel pressure be ?

3. Along the gauge theme, I also need to install an oil pressure gauge, which leads me to the what should my oil psi be at idle and lets say 70mph?

4. Is there any three gauge pod avaliable for the firsts gens? I can only seem to find a two hole.

 

I have a mechanical gauge in the dash. It's a surplus AutoMeter water pressure gauge that matches the rest of my Z-series gauges. No isolater but I have a shut off valve at the engine.

A healthy stock pump will make about 7 psi at idle. It may drop as low as zero under load. You want to see positive pressure but don't panic if its low. Stock trucks do OK with even a little pressure.

A 0-100 oil pressure gauge is fine, a healthy engine will have at least 15 psi at hot idle and run around 60 psi at speed.

Most guys take a dual and single pillar mount and line them em top to bottom as no one seems to make a triple pod for our trucks.
