I may have stumbled upon a solution.
Originally, I had intended to put the 4 port manifold here:
That would make the engine side plumbing pretty simple. All the lines would just run forward and split off near the alternator. Clean and neat.
Then when I looked underneath at how cramped it is inside, I looked at the alternatives.
The path through the wheel well has its own pros and cons. The idea last night was to go through the wheel well only to make the EVAP connections simpler, then mount the manifold on the fender apron sort of close to the firewall anyway. While I think that would still work, I wanted to look closer to see if I could actually make the plumbing work using some fittings with creative shapes.
I made a cardboard template to depict the manifold pattern and stuck it to the inside.
You can see the yellow capped heater lines. They are about twice as long as I’d prefer. I may have to find a way to reflare them. The heater hoses are the easy part. I might be able to find some molded ones with a bend in them. The hardest one is the #6 line. It points straight down.
Using a 22 degree angle fitting like so:
….when attached in a similar fashion as seen, may allow me to make a “loop” and meet the firewall at a 90 degree angle….
Using an elbow…
This might work.
The #10 A/C port is further away from the firewall and the access is excellent.
I could use a straight fitting as shown and make another looped line or use an angle fitting….
This makes only a slight offset if I go with the upper left port on the manifold.
I think this can work.
In keeping with my habit of trying to predict obstacles, (so I can avoid them)… the drawbacks to this are few. I’d have to have the lines crimped and installed before I give the car back to Dwayne. I’d originally thought I’d install the unit and ducts, wire it then his A/C guy would finish the lines and charge the system. To do that now puts a strain on the A/C guy and I’m sure his hourly rate is MORE than mine!
Second possible drawback:
The loop of the #6 hose could put it within kicking range of a passenger. Imagine the mess if a line breaks inside!
Maybe a 90 degree fitting at the EVAP and the manifold both would help?
I’ll test and report back.
