Vacuum hose diagrams, May 2002
These were based on the existing hose locations on my truck, and do not show the California and High Altitude variants.
This diagram (1 of 4) intends to show how the manifold vacuum "joint" supplies vacuum to other locations.
The manifold "joint" is located under the carb, on on the driver's side, and is easily hidden by other hoses. It is easy to recognise with its 6-sided construction, and the 5 hoses coming from it.
The Depression chamber (red arrow), and AAP (green arrow) are visible from the passenger side of the carb.
