How to properly replace the Fuel Pressure Regulator on an Acura Integra?

Turn off the fuel pressure in the system and disconnect the battery cord, remembering to have the stereo's anti-theft code if it has one. First disconnect the vacuum hose and fuel hose from the pressure regulator, then take out the regulator's mounting bolts. You need a fresh 0-ring for installation, and put a thin layer of clean engine oil on it before putting everything back. After installing the pressure regulator, look for fuel leaks.

Acura Integra Fuel Pressure Regulator

The Acura Integra Fuel Pressure Regulator maintains fuel pressure within the sweet spot so the engine receives the proper mixture at any speed. Mounted on the fuel rail by a spring-loaded diaphragm and a vacuum port, the Fuel Pressure Regulator allows gasoline to be bled through the return line when there is low demand, but pinches that passage when the throttle is opened so that pressure increases along with the pulse width of the injector. 1990s Acura Integra cars share this type of rail-mounted back pressure system, but more recent Integra cars with updated fuel systems use a pressure-reducing version of the system that lacks a return line. However, the pressure target for both versions is the same. A failed Fuel Pressure Regulator will stick shut and spike the pressure, resulting in rich running, rough idle, and wasted fuel, or leak or weaken the spring on a Fuel Pressure Regulator, causing pressure to drop and a lean mixture and hesitation. Quick checks include unplugging its vacuum hose to see if pressure jumps, applying handheld vacuum to confirm pressure falls, and pinching the return line to differentiate if the pump is faulty or the Fuel Pressure Regulator. Keeping the Fuel Pressure Regulator healthy allows Acura power delivery to remain crisp, preserves mileage, and curbs emissions from every spirited Acura Integra drive.
