Potential pressure leak?

[coomo]

Hi guys.I did a complete restoration on my 924 turbo 2 years ago.The complete fuel system was rebuilt.
That is new pump, new accumulator, fuel metering head,injectors. WUR either new or rebuilt.The car fires immediately from cold.
However.Im still experiencing some hot start issues.Ill accept it maybe down to fuel evaporation/Air lock.I just want to cover all the bases,before admitting defeat.
One item that ive never seen mentioned is the injector socket (part 931 110 226 01)
The brass injector thread, that locates in a plastic sleeve that screws in head, holding injector.Ive noticed, one or two of mine "spin"
Opnions as to whether this may cause a pressure drop/hot start issue?
