FPR Test Procedure
 

In an ongoing effort to keep costs of repairs at bay I'm wondering if where I can find the procedure for testing the Fuel Pressure Regulator and the Fuel Pressure Damper on my '87 944 NA. It's got 122k miles on it and the AFM and Throttle Body were just rebuilt and resealed. All the vacuum leaks were tested and taken care of. Even pulled the mouse nest out of the Air Filter Box. Getting ready to pull the injectors for servicing/resealing and want to see if the FPR and FPD are working properly or need to be replaced ($200) as well.
