Fuel Pressure Gauge & adapters?

[Caver Dave]

I bought a Actron FP gauge when I was working on the TBI swaps. Did well for the little use it got...

Now I have a couple questions:

• Will 0-60# gauge be fine for early model Cherocars? (IIRC, they run about 45# )
• What about early EFI Fords? (IIRC, 34# is the normal)

Gauge has a "large" female connector (male looks more like an HVAC fitting than typical Schrader). I can find the "Ford" adapter (tire stem-sized Schrader), but wondered if the Ford and Jeep/Chrysler used the same sized Schrader?

Chrysler uses the large adapter like the GM. Ford is the only one with the small adapter. You will be fine with that gauge until you get into the Vortec GM and the LS style engines as they use minimum 65PSI.

Is it just a large Schrader or is like the AN fitting pictured on the gauge hose?

On most models it uses the large schrader on the MPI fuel rail.
