Where are fuel pressure regulators on a 1999 dodge caravan?

The fuel pressure regulator on a 1999 Dodge Caravan is located on the fuel rail, which is usually mounted to the top of the engine. It is typically a small cylindrical device with a single fuel line connecting to it. The fuel pressure regulator controls the amount of fuel pressure in the fuel rail, which in turn affects the amount of fuel injected into the engine.
