Final stages of installing A/C system

[Ray70Chrg]

All major components were new while using original suction and discharge fittings, and the original liquid line. All other fittings and hoses were bought from COLD HOSE. I was able to cut and crimp the fittings and I'm very pleased with the final results. Bought a hydraulic assist crimper from Vevor thru Amazon, and having never done this before, I was amazed how the crimps were prefect every time. The only holdup was a 3 1/2 month wait for the condenser from Classic Industries which, when it finally arrived, was a perfect fit for both the radiator fit and the original discharge fittings. Still have to run some wires for the new cycle switch to the low pressure switch and to the compressor wire. Next will be drawing a vacuum on the system to test how well I put this all together. Fingers crossed.

Great looking Installation......try a nitrogen purge for leak testing b4 pulling a vacuum. A suggestion.....GET RID OF THE RUBBER FUEL LINE AND PLASTIC FILTER AS IT CROSSES OVER THE EXHAUST MANIFOLD. You've gone to a great effort with your investment and Installation....replumb the fuel line with a steel line from the pump to the carb and use a metal can filter.....don't risk a tragedy with a fuel leak on a hot manifold.........just my opinion.....

Thanks Bob, actually I just finished looking at metal fuel lines. They sell both the long line and a smaller loop line which I don't think I need. What happens to the filter when the long line is installed? When I got this car the original line(s) were gone and so was the original carb. Currently I have a Carter afb and most lines say they attach to carter avs 4bl. I assume the afb will also fit? Thanks, Ray

The Carter AFB and AVS are similar but not exactly the same...depending on throttle bores and mounting bolt dimensions. In addition, the AFB has 4-7/8" diameter air horn/air cleaner gasket whereas the AVS has a 5-1/4" diameter air horn/air cleaner gasket. I believe the carbs fuel line connection of either the AFB OR AVS is a 5/16" MALE inverted flare connection. I believe MOPAR'S original fuel line layout, using a 5/16" steel lines ( never use copper or aluminum or rubber), put the fuel filter in the vertical plane near the fuel pump.....from the pump to the bottom inlet of the filter ..a loop line??..and a hard line from the top of the vertically mounted filter to the carbs inlet connection...the FSM shows the approximate layout.....HARD LINES (company)...should be able to offer some guidance.....google the same then call them.....just a suggestion.....there is a big SEMA SHOW in Las Vegas this week (?)....it may be difficult to get a quick answer......anyway.....let us know how you make out.....

Very neat and clean. What refrigerant did you use? And keep us informed how it works.

Not that far along yet. Need to wire up new compressor cycle and pressure switches. The system is now r134a ready, but haven't decided which brand I'll use, if that's your question.

Me personally I’d think it look better if you’d lay the compressor on its side and get the charging port closer to the radiator. You can also adjust your compressor and PS pump to be inline to get rid of that 3rd belt.

The biggest issue I had on my install was bad crimps from the local shop. I did not find that cheap crumpet early enough so I clocked all of my fittings and had the shop crimp them. I have ended up fixing all of them myself with that crimper which works great. If you still have room, I would recommend recrimping the existing fittings also as I had one of those compromised.

Nice job. Take it to a Pro for the Charge and at least consider ICE32.
