I just did a van three weeks ago it was a 94 and ford said they are no longer get them. So a removed some off the lines. Remove the dog house and where the rubber lines connect to the steel lines I cut the connectors of so there is just rubber then got a barbed connector from the hardware stor (4 of them, and 16 hose clamps) about 16 feet of heater hose cannot rember the size. then took about four feet off the steel lines, on both lines, the reason i did not remove the lines is because it runs with the a/c lines to the rear witch if i tried to remove they would have leaked. then i ran both lines down the frame protecting them and connected them the same way at the rear. I used 2 hose clamps with every join. it was doing this or bypassing the rear heater core. |
