4 Bar OEM Fuel Pressure Regulator FPR for Audi S4 2.7T / A6 / Allroad & A4 1.8T


Common failure, see pictures above.  The plastic and diaphram inside fail and let fuel into intake manifold via the vac hose.  If you have a wet vac hose coming off the FPR or you have weird rich running issues or hard hot start issues this is likely your problem.
