- Straight nipple orientation for the fuel connection.

A fuel pressure regulator controls the pressure of the fuel delivered to the injectors, bleeding off excess back to the tank so delivery stays consistent across engine loads. Signs the regulator may need replacing include rough idle, hard starting, or a fuel odor — diagnose the cause first, since these symptoms can have other sources. If a failed regulator is the cause, this unit replaces it.
