1991 F150 vacuum lines

evo-00 · 12-09-2008, 04:41 PM

Can any tell me or give me a vacuum line diagram for a 1991 f150. I need to know where the 2 red lines on top of the intake go to specifically? Also below coil does the green line go on top or bottom of the red line where it plugs in.

Green on top/red on bottom for thermactor. - Off the Vac manifold 1 goes to the EVR & I think the other goes to the soup can on the passenger fenderwell but don't quote me on the last one, the Haynes manual diagram says "to distributor" for 90's thru 95's.
