What is the part number for the EFI vacuum reservoir ("coffee can")?

The vacuum reservoir, nicknamed the "coffee can," is shown as Ford part number 9E453.

Where does the check valve (9A995) vacuum line go?

The diagram shows the check valve 9A995 with a vacuum line routed to the HVAC system.

What part numbers are shown for the EGR system components?

The diagram labels the E.G.R. valve as 9H473, its gasket as 9D476, the E.G.R. tube as 9D477, and the E.V.P. sensor as 9G428.

What does the asterisk (*) next to hose 373046-S mean?

The footnote states that the asterisked hose is "CUT FROM 12226 BULK HOSE," meaning it is made from bulk hose stock rather than being a preformed part.

Which components are on the right-hand vs left-hand side of the engine?

The T.A.B. valve (98289) is labeled R.H. SIDE, while parts 387065-S and *373046-S near the F.P.R. and T.A.D. connections are labeled L.H. SIDE.

This document is an annotated engine-bay illustration titled "EFI Vacuum Lines," showing the routing of vacuum hoses on a Ford EFI engine. Component callouts are given as Ford base part numbers with abbreviated names: the M.A.P. sensor (9F479) connected to the vacuum tree, a check valve (9A995) with a line running to the HVAC system, the E.G.R. valve (9H473) with its gasket (9D476), E.V.P. sensor (9G428), and E.G.R. tube (9D477). A vacuum reservoir (9E453), nicknamed the "coffee can," is shown near the accessory drive area. Emission-control solenoids and actuators are identified: the T.A.B. valve (98289) on the right-hand side of the engine, the E.V.R. solenoid (9J459) mounted on bracket 9H472 with fastener N620479-S (AM-18-B), and the combined T.A.B. & T.A.D. solenoid assembly (9H465). On the left-hand side, lines route to the fuel pressure regulator (F.P.R.) and T.A.D. actuator, with hose/fitting part numbers 387065-S and 373046-S; a footnote states the asterisked hose is cut from 12226 bulk hose. Large arrows indicate hose routing paths across the engine. A reader can identify each vacuum component, its Ford part number, and how the vacuum lines interconnect.
