Evap Core Differences (AC in LS Swapped K10)

[79ShortBox99]

Hey Guys,

I've been reading posts on here for a long time for information on my 79 K10, and it has been the best resource I have found.

I am working on getting all the parts to put a Sanden 508 on the 5.3 that I swapped into my truck. The issue that I am currently facing is my evap core. All of the images that I have seen have two male fittings coming out of the evap core. My connection that goes from the evap core to the condenser is a female connection. I was using the diagrams on L-C Truck and images of similar setups to figure out what line attaches to the female side and I cannot find any other evap cores that have the same fitting on the bottom. All the evap cores I have seen have a male fitting on the bottom. Am I missing something here? I included an image to show the lower fitting.

Note: When I bought the truck, the AC lines and the compressor were already removed so I do not know if there was another component connecting to the female side to the condenser. From the images and diagrams I have seen, it does not appear that anything goes in between.

Any help would be awesome!

Unless it's some sort of dealer-installed a/c, they should all be two male fittings.  Since you're going to be building new lines (to fit the Sanden), I'd just do the male-fitting units to avoid trouble in the future.

Top goes to accumulator, bottom has orifice tube and liquid line. Obviously if you are making your own lines you can cannibalize the OE hose and use the correct beadlock fittings for your compressor.
