Valve for heater core hook up.

[topfuelr473]

I have a 1992 D250 club cab and I am replacing the valve on the fire wall that lets the coolant into the heater core. There are 3 vacuum lines coming out of the fire wall but the squirrels had chewed them up. I would like to know if anyone has a picture of their truck that I could reference to get mine hooked up correctly. Thank You.

This is a W version of your truck (manual w/cruise if it matters). Has only two vac lines...the gray to the coolant hose valve and the black one that wanders over to driver side and I presume is vacuum supply...lighting too harsh to see where it goes. I can't find a vac line diagram for diesel in my FSM but the HVAC section does show the gray. Sorry, mine doesn't have 3. Holler if the photo isn't the area you're talking about.

The black vac line goes to the brake booster valve.
