It sounds like you may have the vacuum lines on incorrectly. The diagram above is for a 2001 2.7L manual. There is more discussion of it here: https://986forum.com/forums/boxster-general-discussions/64576-vacuum-line-clarification.html#post518618

I have seen this before .
are you sure this applies to 2.7 manual transmission?

cause my FPR seems to be coming from top of "J" change over electric valve and other end of electric valve goes to a the Flapper valve !



thanks for all your help.
