*A. Remove the 1/4"NPT socket head plug

located perpendicular to and directly

beneath the factory oil pressure sending

unit. This is found on the driver’s side

below the oil filter.

*B. Thread the supplied 1/4"NPT #4 flare x 90°

fitting into the pressure sending unit mount

using engine oil on the pipe threads. Rotate

the fitting so that the flare points toward

the front of the vehicle. (See Fig. 3-a.)

**C. Remove the oil pressure sender. This is

located the driver’s side of the engine

below the oil filter.

**D. Thread the supplied 1/4" street TEE into the

pressure sending unit mount using engine

oil on the pipe threads.

**E. Install the sending unit and the 1/4"NPT #4

flare fitting into the street TEE as shown

and tighten. (See Fig. 3-b.)

F. Temporarily cap off the flare fitting to

prevent dirt from entering. The oil feed will

be connected at a later time.

Position the fuel management unit (FMU) against the inner fender ahead of

the right side shock tower about an inch from the top. Mark and drill two

holes in the inner fender to mount the FMU. Secure with the sheet metal

screws provided. (See Figs. 4-a, 4-b, 4-c.)

Disconnect and discard the factory rubber fuel return line running from the

fuel rail (the return line DOES NOT have a pressure test fitting on it) to the

steel return line (the smaller of the two) located behind the right side shock

tower using a spring lock disconnect tool.

Connect the FMU inlet hose (the hose that goes to the 90° fitting on the side

of the FMU) to the return side of the factory fuel regulator on the fuel rail.

Connect the FMU outlet hose (attaches to the center fitting on the bottom of

the unit) to the steel return line running to the tank. Make sure hose end is

securely “snapped” onto factory fuel return line.

Secure the fuel lines away from abrasion and exhaust heat with the tie wraps

provided.

Attach the supplied length of 5/32" vacuum hose to the fitting on top of the

FMU. Connect the opposite end of the hose to the factory fuel regulator

vacuum connection using the 5/32" TEE provided.
