1989 F150 351W FI, need vacuum diagrams/pictures please
Hi guys and gals,
I've got a new toy, an 89 F150 with the 351W, FI. I'm having a lot of trouble getting good diagrams for the vacuum routing, and i've still got some questions left.
Ideally, someone with the same engine/configuration could post a picture of their correctly working setup, and I can just copy that.
Specific current questions:
The "Coffee can" on the passenger side wheelwell is a vacuum reservoir can, and that's supposed to keep the HVAC system from losing vacuum under heavy engine load, right?
The small box protruding from the A/C and Heater area in the back passenger corner of the engine compartment; what is it for, and where is the vacuum line from it supposed to connect to?
I've seen that thread before, and while it's got a lot of useful information, it doesn't cover some of the pressing questions I have.
Let's start with this one:
The small box on the outside of the HVAC box in the back passenger corner; mine has a vacuum nipple, but isn't connected to anything, and I can't figure out where it's supposed to connect to. I also have very little heat coming out, but my radiator is full, and everything else HVAC wise works correctly.
