3/32" holes and secure the unit with the sheet metal screws
provided. (Temporarily placing the washer reservoir back

C. Connect the FMU outlet hose to the brass #4 flare fitting

located before the secondary pump inlet.

D. Attach the supplied vacuum line from the fitting on top of the

FMU to the small vacuum fitting on the driver's side of the
intake manifold. See graphic.

E. Use tie wraps to secure the lines.
F. Reinstall wiper washer reservoir, lines and wire connections.

12. IGNITION COIL RELOCATION
