D100 Build: A/C & Heater Hoses

I mounted the drier on the driver side inner fender, near the front. It’s tucked out of the way and offers an easy route for the -6 hose coming out of the condenser.
Doing the robot.
I don’t have any of the hoses tied together yet, but this will be the route they’ll take. Missing from this photo is the heater hose from the water pump.


II Much makes these handy anodized aluminum adapters to go from #10 heater hose to -10 EZ-Clip. I used a small section of rubber hose off the water pump, and then will use the Vintage Air reduced diameter hose to match the A/C hoses.
Check out the YouTube video on how to make the connections. It’s really, really easy!
The II Much bulkhead system is one of my favourite parts on this whole truck. I have one more hose to run, then I’ll be able to install the hose separators to really clean it up. It’s designed to fit the EZ Clip hoses, so you’ll have to decide whether you want to run normal heater hose from the water pump & intake up to the bulkhead, then use the adapters to switch to EZ Clip and go through the bulkhead, or run EZ Clip hose all the way from the evaporator to the engine. If you do the latter (my method), keep in mind that the heater control valve needs to be plumbed in the line coming from the intake, but the valve is designed to use normal heater hose. You’ll need to use an adapter before the control valve to convert from -10 to standard heater hose.
I thought there was going to be a fair bit of room under the dash! Get everything mounted that could possibly be an interference point. You can see the charge port on the -10 hose – check with the people who will be charging your system to see if they are ok with having one charge port inside the vehicle and one in the engine compartment.

Here’s a video showing the process of making a connection with the EZ-Clip system:
