91157352502 Porsche 911-930 AC Barrier Hose

Griffiths’ Kuehl brand 91157352502 Porsche 911-930 AC Barrier Hose assembly connects to the end of the suction line coming from the compressor, PN 91157314903, and the evaporator outlet.  This hose is located in the smuggler’s box in the front trunk.

The original factory hose tends to get damaged by age.

Replacement of the 91157352502 Porsche 911-930 AC Barrier Hose assembly requires the following:

  1. Recovery of refrigerant from the system prior to removal
  2. Disconnecting the ends at the evaporator and the end connection with hose PN 91157314906.
  3. Installing a new receiver drier.
  4. Evacuation, charge and testing of the ac system.
