Heater hoses

I have been working on the trunk area and am almost finished. My current project is completing the installation of all hoses to the fresh air box. Some of these hoses are for fresh air and the others, for defrost.

Before, vacuum cleaner hoses, rust, taped up hoses, broken fresh air box. 
Time to get to work.

The hoses leading to the heat tunnels are important, and the most difficult to replace. These are to the left and right of the trunk on the passenger and driver side. Basically, they run between trunk and the door, down the length of the door where the door hinges are. They are hard to get to and made of paper. Chances are, yours might be just as shredded as mine were and need replacing.
The important thing is to ensure you don’t throw away the old ones until the replacements arrive. I’ve purchased mine from both Jbugs.com and westcoastmetric.com.
Here’s how they should be set up:When installing, clean out all disintegrated hose material down and around the heat channel. These run up behind the trunk and along the left and right sides of the floor boards. There is a viewing port about an inch in diameter on the post just above the bottom door hinges and toward the wall between the seats and trunk (you’ll have to pull back the carpet to find them). Use a screw driver, knife or something sharp to scrape away the old paper hose and glue. Use a shop vacuum to suck away the many years of junk that may have fallen into it. I found old pencils, bolts and waded up old papers.

Next cut the hoses to the proper lenght. They always come too long, so be prepared to cut them to the right size. The hose leading from the plastic hose junction piece to the bottom should be about a foot and a half long. Measure and install those hoses first as they are the most difficult to install. The ones I bought were not wide enough to fit over the channel or the plastic piece. I had to improvise tape the hose to the plastic piece. At the heater channel, I taped a smaller diameter piece to taper it into the hole. It wasn’t an easy fix, but it’s functioning. 

Hoses are cut and installed. Not pretty, but functional.                                                                                 The tape is there because I crushed the hose with the trunk hinge.

 Then hook up the other hoses. Be sure to slowly close the hood once installed. If any of the hoses are in the way, the trunk will crush them.

The trunk is now complete.
