New reproduction air conditioning suction hose for all 1971-73* Mustangs & Cougars with factory stock V8 engine (small or big block V8) and 70-71 Torino, Ranchero, Montego, Cylcone (big block V8 only), all with factory installed air conditioning. This is the hose that connects to the service valve on the compressor, to the expansion block fitting attached to the evaporator, at the firewall. Built using the correct nylon hose material. * NOTE; some late 1973 models do not use service valves. To use this hose in such instances, a service valve (available in our eBay store) will need to be purchased. We can also custom restore your original hose if desired.
