1972 k10 front differential vent hose and tube source

I need to replace my vent hose ( very dry rotted and it broke off) Where can I get the correct hose? Also are the vent tubes available?

Thanks in advance,
Ray

I used fuel lone for the hose.

The vent is GM Genuine Parts 25892279 Multi-Purpose Vent. Dorman has the same vent in white. They call it a transmission vent I believe.

Hi Larry,

My original hose appears to be 5/16. Does that sound correct?

Thanks,
Ray

Can anyone confirm exactly where the front axle vent hose mounts to the frame?

Where Larry has it pictured is correct as far as I know. Both my K10 and K20 are attached in the same place.
