Transfer Case Switch Vacuum Adapter

1992 S10 4x4, 4.3L, TBI

I have a vacuum leak at the transfer case switch. The switch is brand new, but the adapter that ties all three vacuum hoses together into a set is leaking. It is old and loose and I need a replacement. Any ideas where I could find this? Is the dealer the best bet? Would they even have it? Is there something else I could do to modify this to make it work?

Thanks.

That old it is going to be hard to find.
If you are luck is with you a bone yard may have it.

I just cut it off and hook the vacuum lines direct on to the switch.
Most parts places have vacuum lines and splices for them if you need them.
