Fuel Pressure Regulator

Hello, where is the Fuel Pressure Regulator on my model explorer? It has the 4.0 L V6 OHV engine. I was told it was on the fuel pump assembly but I have been told other things. Could someone tell me for sure?

The regulator actually is not working properly. It starts but it is a little rough on cold starts. The cranking amps of the battery is great.

When the engine is off there is no pressure.

that is most likely the pump. there is a check valve in the pump that is common for failure. did you pinch off the lines to confirm??
