1997 Chrysler Concorde fuel pressure spec.

The pressure will vary depending on intake manifold vacuum. That's why there's a vacuum hose on the regulator.

I've only heard of one regulator failure on a Chrysler product, so if you have a fuel pressure issue, the pump is a better suspect. What kind of problem are you trying to solve? My '88 Grand Caravan calls for around 50 psi, but the engine will run fine with no symptoms down to as low as 20 psi. We don't typically use fuel pressure readings for diagnosing a problem. That is not the case with other brands. For example, there are some GM vehicles that won't start if the fuel pressure is just two or three pounds low.
