Should A Fuel Pressure Regulator Hold Vacuum. If your base fuel pressure is 42psi, and the engine is applying 8psi of vacuum/suction, then the effective fuel pressure at the injector outlet is 42 + 8 = 50psi. Return style systems hold a big advantage in that with a vacuum/boost referenced fuel pressure regulator, the system can maintain a. I don't think the issue lies with the fuel regulator. The idea of the vacuum. I'm diagnosing some strange idle problems and one of the things i did was put a mighty vac on the fuel pressure regulator. Only excess pressure should flow past the regulator, though. This reduces weight, complexity (routing a return line can prove to be difficult), and expense. Locate the fuel pressure regulator: Adding to help clarify a couple of points. The fuel pressure regulator is typically located on the fuel rail, near the fuel injectors or the fuel filter. In that case, you put a fuel pressure gauge on the engine at the schraeder valve (if so equipped) and check the fuel pressure at idle and ensure you have the proper pressure. Requires no fuel return line and fittings from the regulator to the fuel tank. The fuel pressure regulator relies on vacuum pressure generated by the engine to help maintain system pressure and predict what fuel demands are about to be placed on the. A vacuum/boost reference port allows the regulator to compensate for boost pressure with forced induction applications (g). This is often termed as.
