★ Top Answer
In the 2007 Nissan Frontier, the fuel pressure regulator hose connects to the intake manifold, and the regulator assembly is mounted on the fuel rail. Signs of a compromised regulator include black smoke from the exhaust, gas leaking from a vacuum hose, darkened spark plugs, misfires, decreased engine power, reduced acceleration, and loud pump noise. The fuel pressure regulator determines the amount of gas sent to the engine's injectors by using information from speed and pedal sensors to adjust the air/fuel mixture in the combustion chamber. If the engine is running too rich or lean, it can affect performance and fuel economy. Replacing the fuel pressure regulator in the Frontier at a dealership typically costs between $550 and $830 for parts and labor.
