INTRODUCTION Thank you for selecting the Edelbrock Pro-Flo 3 EFI system. This is an electronic fuel injection system intended for V8 engines originally equipped with carburetors. The Pro-Flo 3 EFI system can be paired via bluetooth connection with an exclusive tuning software, E-Tuner, which is available as a free app for most Android-based tablets and smartphones. The use of a laptop PC is not required for tuning.
AUTOMATIC TRANSMISSION CHECK For best performance, economy, and emissions, the transmission kick down and shift points must be checked before and after the ProFlo 3 EFI installation. SPARK PLUG WIRES High EMI suppression spark plug wires are necessary, do not use solid core spark plug wires. Resistor type spark plugs are necessary. EXHAUSTS SYSTEM For best results, headers are recommended.
FUEL SYSTEM REQUIREMENTS The Pro-Flo 3 EFI system requires a high pressure fuel system providing 43-45 or 58-60 psi of fuel pressure with a flow rating of 57 GPH (215 liter/hr). If you purchased a kit without a fuel system, the following recommended options are available separately. Part Number 3604: Return-Style Fuel System: Can use any fuel pump with a minimum flow rating of 57 GPH (215 liter/hr). Fuel pressure must be regulated to 43-45 or 58-60 psi.
PRIMARY KIT COMPONENTS (Images are for reference only and may not represent actual components.) Item P/N QTY.
PRO-FLO 3 4150 STYLE MANIFOLD - COMPONENT LAYOUT The Edelbrock Pro-Flo 3 EFI system delivers fuel and air to the engine via an induction system consisting primarily of a 4-barrel throttle body, dual fuel rails, and eight fuel injectors. The induction system is fully assembled, tested, pressure checked, and flowed at the Edelbrock Factory in Torrance, California. Avoid disassembling these components if possible.

PRO-FLO 3 XT MANIFOLD - COMPONENT LAYOUT The Edelbrock Pro-Flo 3 XT EFI system delivers fuel and air to the engine via an induction system consisting primarily of a traditional 90mm throttle body, dual fuel rails, and eight fuel injectors. The induction system is fully assembled, tested, pressure checked, and flowed at the Edelbrock Factory in Torrance, California. Avoid disassembling these components if possible.

WIDEBAND OXYGEN (02) SENSOR INSTALLATION PROCEDURE The 02 sensor must be installed in the exhaust system using the supplied 02 sensor bung from Hardware Bag #1. The 02 sensor is required as it measures the oxygen content of the exhaust gas, which is used by the ECU to manage fuel delivery under closed loop control. NOTE: It is suggested that the 02 sensor bung be installed by a professional muffler shop prior to the installation of the Edelbrock Pro-Flo 3 EFI system.
DETERMINING HOOD CLEARANCE 1. Prior to installing the Pro-Flo 3 EFI system, it is highly recommended to verify that you will have enough hood clearance. 2. Using modeling clay or putty, not included, make five small cones about 2-3 inches high. 3. Position the cones on the air cleaner at front, rear, each side, and on the center stud. 4. Close the hood to locked position and re-open. 5. The height of the cones indicate the amount of clearance between the hood and the air cleaner.
PRO-FLO 3 EFI INSTALLATION NOTE: Though visually different, the installation procedure is relatively the same between manifolds using 4150 style throttle bodies and XT type throttle bodies. 1. Disconnect the battery. Drain the radiator coolant (radiator drain plug is typically located on lower right facing engine). WARNING! Do NOT drain coolant while engine is hot. 2. Remove the gas cap to release any fuel pressure present in the system.
14. Wipe down the intake manifold’s mating surface with lacquer thinner (Figure 5). Carefully position the intake manifold onto the cylinder heads. Figure 6 Figure 5 15. Torque all manifold bolts in a criss cross pattern starting with the inner bolts and working outwards. Refer to the vehicle’s service manual for proper torque spec and procedures. NOTE: On most applications, removal of fuel rails prior to installing the manifold assembly is not required. 16. Reinstall the valve covers if removed.
22. Find a suitable mounting location for the ECU. This should be on the same side of the vehicle as the 02 sensor. Recommended mounting locations are the fender well, inner fender panel or inside the vehicle on the passenger side kick panel. Be sure the O2 sensor connection reaches the main harness connector. NOTE: It is recommended to mount the ECU in a location away from excess heat, vibration and possible water exposure. 23.
FAN & A/C TRIGGER INSTALLATION Three pigtail leads are provided in Hardware Bag #2 to trigger the electric fan(s) and A/C kick up, if so equipped. The Fan trigger outputs from the ECU are low current switched GROUNDS that require a 30 AMP Automotive Relay (not included) for each output. NOTE: DO NOT connect Pro-Flo 3 ECU fan outputs directly to fan motors. DO NOT connect A/C compressor clutch switch directly to the Pro-Flo 3 ECU. DAMAGE TO ECU WILL OCCUR.
