That is awesome that you got the A/C going in your truck. I'm hoping to have mine done this week and be able to test it out before fall arrives
I'm sure it's annoying that it isn't working 100% correctly under hard acceleration, but I'll bet it's still better than no A/C! I'm sure you'll get it sorted out.
I'm super excited that I have the A/C working. Going from the point of buying this truck with the massive hole in the firewall and two A/C boxes to piece together to create a functional unit and no prior knowledge of the wiring and vacuum lines to the point where I am today is a huge accomplishment for me. Growing up restoring classic Mustangs has helped in being familiar with a lot of areas on these trucks but the knowledge required for the various nuances of these 70's trucks vs the 60's cars is definitely higher. Here's a shot of my A/C belt (mostly for my reference):
I've had the vacuum leak I think since day one. It hasn't bothered me too much and really doesn't matter much to me on the A/C front. I think the vacuum leak is the main reason why I haven't been able to get the FiTech to work so that's why it concerns me. With the carburetor on, the truck runs great even with the vacuum leak. I'm a bit puzzled because if the truck runs fine with the carb and vacuum leak, I'd think the fuel injection system could also handle it to the point where I could get it to at least idle properly but that hasn't been the case yet.
I dropped my 78/79 power steering gearbox off at a local power steering specialty shop today. The lead time is 10-14 days for it be get rebuilt. Once its done I'll drop my truck off at my friend's shop for him to do the front cross member cutting and other welding needed to get the box mounted up.
Finally, here's what I came up with for a coil mounting. However, I need some advice. I put a strip of self-adhesive sound deadener on the coil to make it fit snug in the holder. It's held in place pretty good but just in case it decides to try and vibrate free I found this piece of metal that I think goes to the A/C system on my Mustang to use to prevent the coil from vibrating out in any way. Not pretty, but functional.
Here's what I'm not sure of. I've never had this particular coil mounted horizontally before. It's always been vertically mounted. How do I know whether I'm risking a fire from the coil being horizontal? I know I've read about them catching fire due to the oil coming out and flaming up.
