Updated Service Information
Some 2001 model year 3.8 L (RPO L36) engines have a revised fuel pressure regulator, which increases operating pressure. The pressure increase is due to the use of MULTEC II injectors. For these applications, the fuel pressure operating range is approximately 358-388 kPa (52-59 psi). Note that this new regulator should read approximately 380 kPa (+/- 2%) with the vacuum line disconnected.
The use of other regulator part numbers with the applications listed above could result in incorrect fuel metering, increased emissions and driveability concerns.
Important:
^ The revised fuel pressure regulator IS NOT interchangeable with past model applications. When replacement is necessary for the above listed applications, use only regulator part number 17113660.
^ The revised fuel pressure regulator IS NOT used on 2001 Chevrolet Camaro and Pontiac Firebirds equipped with the 3.8 L (RPO L36) engine.
Refer to Service Repair Information Engine Controls section for detailed diagnostic and repair information on fuel system related concerns.
