| This hose is an exact duplicate on both the OD and the ID compared to the original factory hose. This hose is sold by the foot only and we have a minimum purchase of at least 10 feet. Under the hood these cars use about 30 feet of hose. That doesn't include the hose that is located under the dash, or the rest of the hose that goes through the firewall. The extra small vacuum hoses on your intake manifold that go to your heater/AC systems on the 74-89 z cars is also referred to as HVAC hose. It is very difficult to find the correct size but that's why we carry it in stock. We can ship this hose in a padded envelope via the postal service, and cost anywhere in the lower 48 will be $8.50 for up to 50 feet of hose. Last update 05/10 |
