Vacuum Wiper Hose Routing

[Gator Alum]

I would like to keep my vacuum wipers. Yes I know they can be problematic and electric is the way to go, etc. etc. But I think I'd like to give these a try first. The wipers rise up and then just stay put. When I turn the switch off, they go back down.

Currently I have two hoses coming out the back of the wiper motor. One goes to the intake manifold directly below the carb. The second comes through the firewall and just dangles there from the PO. I've read about them being hooked up to the fuel pump, but mine obviously does not have those connections. I cannot for the life of me find where the second hose should be hooked up.

I've searched and searched and searched... any help would be appreciated as always!

i looked in the factory assembly manual section 1 sheet 54
there is no 2nd line on any series 3000 to 6000 truck
i would have scanned it for you but it was a pretty basic sheet
just a single line from the wiper motor to the fitting on the manifold

Ogre- thanks for checking. I found that page too over the weekend. That is what really has me scratching my head.

I think I need to crawl under and find what model motor it is and start searching that way. Was just hoping maybe someone had the stock set up still.
