Leak test of VI inlet at 7890 gas chromatograph

Dear Agilent,

Can I use the leak test" procedure found at the 7890 service mode button to test for leaks in a VI inlet as well as for S/SL, MMI or PTV inlet? A gas sampling valve (GSV) is connected between the VI-inlet EPC module and the VI inlet interface body. If the internal GC service button is not usefull for this purpose, how do I then control for possible leaks at the VI-inlet?

Link to 7890 GC service mode leak test procedure.

Best regards -
