Fuel Pressure Regulator Porsche Fuel Pressure Regulator On Rear Side Of Rail 0280160227 Part No: 94411019803Quantity: Invalid Quantity. Special Notes The regulator's job is to keep the pressure in the fuel system to a constant psi. Id does this with the spring-loaded diaphragm that controls a valve. The valve when opened by excessive pressure in the fuel lines uncovers a fuel line that returns excess fuel to the fuel tank. The vacuum connection is there to help reduce emissions during deceleration. During deceleration the vacuum connection serves to open the fuel return valve wider which reduces pressure in the system and prevents excess hydrocarbon emissions due to less fuel being injected as a result of the lower pressure in the system. This is very nicely designed device in that it provedes for an automatic self-adjusting pressure regulator and emissions control device all rolled into one. The simplicity of the design also contributes to it's reliability. We offer the OEM Bosch unit! Application Notes The regulator's job is to keep the pressure in the fuel system to a constant psi.
