The booster has 2 ports one marked in and one marked out. The truck has a 90* hose-barb fitting at the intake manifold which is split at a tee one to the trans shift solenoid(turbo 350) and one to the wiper motor. there are two ports on the wiper motor, but I am only using one and it works this way (just not well).

Ran another line from the pump to the wiper. That's all I have for lines, but my wiper motor has issues. I did get good vacuum. | | | | | Joined: Jul 2010 Posts: 127 Wrench Fetcher | | Wrench Fetcher Joined: Jul 2010 Posts: 127 | Thanks for the info. I will give it a shot. Incidentally does it matter which port goes where. One is marked "in" and the other is marked "out" so i would guess "in" to the intake and "out" to the wipers?

I will give it a shot. Incidentally does it matter which port goes where. One is marked "in" and the other is marked "out" so i would guess "in" to the intake and "out" to the wipers? Air is sucked in to the wiper motor. I would think you need a line from there to the 'in' port on the pump. The 'out' going air would be sucked into the intake. | | | | | Joined: Mar 2005 Posts: 1,636 'Bolter | | 'Bolter Joined: Mar 2005 Posts: 1,636 | Easiest way is to pull a hose off the pump and see if it sucks or blows. If it sucks, it goes to the wipers. If it blows, it goes to the manifold. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 |
Good answer, Roy.
I have seen three different "codes" for the two ports on dual-action pumps: port "1" and port "2"; port "In" and port "Out"; and, no labels at all.
Another good answer was recently posted in response to this conundrum: connect them one way and if it does not work, connect them the other way.

LOL... Good answer here too! Stay away from rotating elements in the process, though! Jerry | | |
