91157314905 Porsche 911-930 AC Barrier Hose

Griffiths’ Kuehl brand 91157314905 Porsche 911-930 AC Barrier Hose. Replaces PN 91157314902.   Used on  911, 1970-1983 and 930, 1974-1977; having Behr Evaporator Boxes.   Compatible with both R12 & R134a refrigerants.  This hose connects between the evaporator outlet and compressor inlet on LHD models.    This hose attaches to outlet port on the evaporator and then runs downward through a slot on the LH front side of the "smugglers box" (located in the trunk), it then is routed under the steering rack and moves along the bottom of the tub toward on the RH side adjacent the oil cooler lines, and continues under the RH rear inner fender wall seam and passes through a slot to the engine compartment near the heater box and RH shock tower and connects to the York Compressor. On RHD models there there is an extension hose attached between its end and the evaporator outlet.  This hose can also be used with factory York or Sanden and Seiko compressors with flare fittings.  The original factory hose tends to get damaged by car lifts near the RH rear lift point. Replacement of the 91157314905 Porsche 911-930 AC Barrier Hose assembly requires the following:

1. Recovery of refrigerant from the system prior to removal
2. Supporting the vehicle on a lift, or 4 jack stands.
3. Removal of the splash cover under the cross member.
4. Removal of rear RH tire.
5. Disconnecting the ends at evaporator outlet and compressor inlet (use two wrenches to avoid damaging evaporator fittings).
6. Removal of all hose clamps under the vehicle tub from the rear to the front.
7. Installing a new receiver drier.
8. Evacuation, charge and testing of the ac system.

Note

• The original factory hose used copper crush washers at the fitting ends.  Copper crush washers are not needed with Griffiths’ Kuehl brand hoses.
• If you have a RH (right hand drive) 911 or 930 you will also need to order a hose part number 91157352501 which connects between hose 91157314905 and the evaporator
• Please verify that evaporator and compressor both have flare fittings, and verify the routing of the hose. Some hose routings pass through the front RH inner fender wall rather than as describe above
• Please contact us for further assistance if your hose fittings or routing are not as describe above.
