Why wouldn't the traditional residual pressure test be enough for starters?
If you hold 20-ish + pounds that means those individual components are fine.

Mr. Bob K.,
You have been behaving quite well the past few weeks and keep it that way. And I will give A+ for conduct. Anyway, if you performed the traditional residual test (pressure gauge installed between WUR & FD), it won't identify which one is the culprit. And like most people believe, the FA would be the culprit of choice and replace a good working FA with a new FA and the problem could still persists. Sometimes they get lucky. But you can not rely on luck all the time.
While some trouble shooters would blame the FP check valve as the culprit. Replaced the old FP check valve with a new one and the problem could still persists. This is good for the mechanics or shops because they are paid for the time they work on the car but not good for the pocket of the car owners.
CIS is an old and antiquated technology but if maintained properly, it will perform flawlessly and reliably for a long long time. Problem is that younger generation mechanics are less familiar with this old system. A service manager for a well established and known Porsche/Audi dealership owns an SC. He has more than twenty mechanics at his disposal, and none of them could fix his CIS.
