Heater Hose for all water cooled Vanagon from 83.5-91 This is the bulk heater hose that runs from the front to the rear of the Vanagon. It is just straight hose so at the very front, you are going to need to purchase the preformed hoses that go to the front core. Don't worry, we sell those too. The price is by the foot so measure your van and buy accordingly. I seem to remember that around 21 feet does the feed and return hoses from the engine to the front.
