My question is how does the vacume line hook up? Of course there was no instructions included with it and my assembly manual, (which I now can't find...must be in the garage) only says that a line comes from the manafold and the other goes to the wiper motor. This seems pertty basic but just so I don't mess it up I want to confirm that this means that the vacume line coming from the manafold that normally goes stright to the wiper motor will now run to the vacume pump on the DA fuel pump and then a line from the DA fuel pump to the wiper motor? Thanks for the help!  | | |

That way the manifold is working as a fore-pump for the fuel pump. I also oiled the wiper motor. They work great. 1948 3/4-Ton 5-Window Flatbed Chevrolet 34 Years.

As mentioned, take the hose from your manifold to one side of the DA pump. You can tell which side it should be on by hand actuating the pump lever. The side that sucks is the inlet and the side that blows is the outlet. Take the outlet to the wiper motor. If you get them reversed, you'll be able to tell. | | |
