The only black thing on the firewall is the vacuum brake assist. The hose I
was talking about drops down from the firewall and heads toward the rear of
the van. I haven't been able to get under the van yet to see where it
No. It drops down below the floor and heads back. The van isn't here now
so I can't trace it out. But in the engine compartment, that tubing goes to
the evap solenoid or whatever that valve is called. The other tube out of
the solenoid goes to the air intake.
