Vacuum Lines

[PICKUP6772]

Hey gang.
Went to fix a broken vacuum line coming off the sensors on the right fender on my 89 GM. It got as far as the whole set-up just disintegrating away. It has 4 hoses/tubes (RED, BLACK, WHITE, GREEN) coming off the sensors, to a plug/connector that hooks up to the main vacuum harness on the engine. If anybody has one, or at least the original FORD number for me to track it down, it would be appreciated. I already checked with WAGONMAN first, and he can't help me on this.

Looking to replace the lines or sensors??

The lines. The plastic completely fell apart.

Doubt the original lines are going to be available. Think you're looking at generic replacement vacuum tubing. Maybe someone else can tell us differently??

Just cap it all off on the engine side for now, those only control your EGR and smog solenoids. It would be much easier to just replace with rubber line - if you can still read the map on the fan shroud sticker you can go by that.
Or, if you can still see where the red lines go, those will be the ports of the solenoids that take engine vacuum. Then, one line will run from one of them back to the EGR valve on the engine, then the other should have two lines coming out, one going to either smog valves plumbed into the 1" metal smog pipes around the passenger exhaust manifold. Hopefully enough is still in tact to let you see where they go.

all of the plastic is pretty much toast by now. I replaced mine with rubber tube and color coded it with small zip ties in the original color to ID the lines. Heat shrink tube would also work well for color coding.
