should be a quick one
 

Can someone tell me what this is? Hose on the right is open-ended and terminates by the headlight, and the other hose goes to the firewall. Driver side 78 k20. Sorry that the pic is crooked, tried everything to straighten it.

That's the a/c accumulator, I think. You have an A/C truck with no condenser in front of the radiator. Correct?

Believe so. I will look when I get home. it confused me because I am the second owner of the truck, and forgot it even had a c. Most of ac equipment is missing. The only thing that really tipped me off was the york compressor.
