Is that a fuel pressure gauge connected to the fuel pump? why do you have it there? Didn't want to install a gauge in the engine bay?

For all the wires, I am thinking about putting a small auxiliary fuse box in the trunk, in addition to the GM EFI harness in the RF engine compartment. I have several areas I need to pass harnesses through the body. I haven’t decided if I want to use just a simple grommet, or spring for nice MS style circular connectors. I have a lot to think about.

Could you use VA's EZ-Clips and hose instead of hard lines under the dash? Do they make the -6 and -10 hoses to match their connections?

Just thinking that would save a lot of time with fab work ... just measure and cut em, right?

Great job with the car .... keep the updates coming!

Hey Michael,

There are so many ways to do this. The VA kit comes with tubes that will go out the heater hole. They are in a diamond pattern and would not work on the vertical bulkhead which I wanted. I think a lot of guys use hose assemblies. Some go through the old blower hole to keep away from tight bends. If you use the VA Gen IV, the heater lines are really close to the firewall and since I set the bulkhead in a little, I just thought it would be too hard to make the tight bends with hoses that are a little fatter. I also shoved the evap. unit as far forward to save as much of my glove box as possible. Everything is really crammed in there!! So look into that. Whether you use EZ-Clip or some other hose system, I think you will need a low profile 90deg fitting to use the bulkhead with hose. The EZ-Clip hose ends have two O-rings and the fittings seem pretty long. For tight spaces there may be better options. Hope that helps!

I didn't work on the car last weekend because I was camping and MTB riding in Northern AZ. I have been playing in OnShape to design a duct that will work with the stock 67 Center AC vent.



It may not work out but the plan is to make something that can be 3-D printed and replace the bulky and expensive factory part below.



This will hold the round air diffuser in place like the factory duct did when it is finished and snug up the round part to prevent rattling around. Here is what the factory vent looks like. You can see I just copied the mating shape.




I need to finish this because it is taking too much time and I want to get back to other things. Anyway I will post up photos if it works out well and probably even if it doesn't!

Randy so sorry I missed your question. I guess better late than never. That is the fuel pressure sensor for the Vaporworx controller. They want it as close to the pump as possible to avoid pressure fluctuations.

Your car is coming along nicely. My son lives in Phoenix and I am there often, I would love to see your car in person.

That would be good. I recommend when the weather cools off this Fall. I haven't been good at getting out there the last few weeks. Dog days got me down!

[SlowProgress]

I haven’t gotten out in the garage much so I have been playing with 3-D CAD. I always wanted to know how to do that but never sat down long enough to learn the basics. Here is the model I made of the 67 Camaro center A/C duct duct assembly.



This thing morphed over several weeks and I honestly don’t know how many learning hours I have in it. I just measured and drew up the vent parts and then figured how to make a duct that will match. The duct has little fingers that hold the vent wheel in place so it doesn’t rattle around.
I printed a version to check the idea out and it works pretty well.



Based on the fit I will make a few changes like the diameter of the hose connection and length of the fingers. The final version will be printed in ABS because the melting temperature and strength are higher.
Yes I have too much time in this but it gave me a good opportunity to learn something new and find the relative cost to have small pieces like this printed (about $30-40 in PLA material). Also, now I have a model if I ever want to make any changes to it. I will admit that 3-D printing in various materials sort of appeals to me!

I will try to get out in the garage and do some real work next week!!

[SlowProgress]

I got out in the garage for a few hours to clean up and check out how all the A/C hoses will route.
The home designed center duct seems to work fine.



I was able to get the hoses routed to the OEM style vents fine



As hard as I tried I could not get the hoses on the defrost ducts because it was too hard to get fingers around. I realized that the hoses can go on before installation and then bend the hose back to reach the fasteners.



Pretty much looks like spaghetti under the dash now.



I think it all works out. I will buy the Instrument cluster from Dakota soon to make sure I have a home for the controller and those wires.

I have the cut down OE glovebox in and I will post up how to trim that to work with the Vintage Air setup soon. I am taking some mountain bike riding time off this weekend. Hope everyone has a good Labor Day weekend.
