I'm curious as to what the stock fuel pressure in a 02 s2k should be in psi. I'm planning to add a fuel pressure gauge this week and want to make sure I purchase one that will provide me with the proper range. Thanks

 

47-54 psi with vacuum hose disconnected from regulator.

 

Thanks!

 

41 to 52 psi with stock fuel pump

46 to 56 psi with Vortech kit - Walbro Fuel Pump

Defi Pressure Sensor.
