4. Installation
Proper installation is critical for the performance and longevity of your Edelbrock 1792 Electric Fuel Pump. Refer to your vehicle's service manual for specific fuel system and electrical wiring diagrams.
General Installation Steps
Preparation:
Ensure the vehicle is parked on a level surface with the engine off and cool.
Disconnect the negative terminal of the vehicle's battery.
Relieve fuel system pressure according to your vehicle's service manual.
Drain the fuel tank if necessary, or ensure fuel levels are low to minimize spillage.
Mounting the Pump:
Select a suitable mounting location away from heat sources and moving parts, preferably below the fuel tank level to aid in priming.
Use the provided mounting brackets to securely fasten the fuel pump to the vehicle chassis. Ensure the pump is mounted in a manner that allows for easy access to the inlet and outlet ports and electrical connections.
Fuel Line Connections:
Connect the fuel supply line from the fuel tank to the 1/2 inch NPT inlet port of the pump.
Connect a new fuel line from the 1/2 inch NPT outlet port of the pump to your external fuel regulator.
Ensure all fuel line connections are tight and leak-free. Use appropriate thread sealant for NPT fittings if recommended.
External Fuel Regulator:
Install an appropriate external fuel regulator downstream of the fuel pump. The Edelbrock 1792 is factory preset to 12 PSI and requires an external regulator to achieve the desired fuel pressure for your engine.
Follow the manufacturer's instructions for the external fuel regulator installation and adjustment.
Electrical Wiring:
Wire the fuel pump to a switched 12-volt power source, typically through a relay and an appropriate fuse (e.g., 15-20 amp).
Ensure the wiring gauge is sufficient for the pump's current draw.
Connect the pump's ground wire to a clean, secure chassis ground point.
All electrical connections must be secure and protected from moisture and abrasion.
Final Checks:
Double-check all fuel line connections for tightness.
Verify all electrical connections are secure.
Reconnect the vehicle's battery.
Turn the ignition to the "ON" position (without starting the engine) to allow the pump to prime and check for any fuel leaks. Address any leaks immediately.
Start the engine and re-check for leaks and proper fuel pressure.
5. Operation
The Edelbrock 1792 Electric Fuel Pump is designed for consistent and reliable fuel delivery. Once properly installed and wired, its operation is largely automatic, controlled by the vehicle's electrical system.
How it Works
When the ignition is turned on, the fuel pump receives electrical power, activating its internal motor.
The motor drives the carbon fiber vanes and composite rotors, drawing fuel from the tank through the 1/2 inch NPT inlet port.
Fuel is then pressurized and pushed out through the 1/2 inch NPT outlet port towards the external fuel regulator and then to the engine's fuel system.
The external fuel regulator maintains the desired fuel pressure for optimal engine performance, returning excess fuel to the tank.
The pump's unique design ensures efficient cooling of its components, contributing to its longevity and consistent performance, even under demanding conditions.
The pump's quiet operation (4 to 14 dB quieter than conventional models) means you may not hear it as prominently as other fuel pumps, but its consistent flow rate of 160 GPH ensures your engine receives adequate fuel.
6. Maintenance
The Edelbrock 1792 Electric Fuel Pump is designed for minimal maintenance. However, periodic checks of the fuel system are recommended to ensure continued optimal performance and safety.
Inspect Fuel Lines and Connections: Regularly check all fuel lines, fittings, and connections for signs of leaks, cracks, or wear. Replace any damaged components immediately.
Check Electrical Connections: Ensure all electrical wiring to the pump is secure, free from corrosion, and properly insulated.
Fuel Filter: Ensure a high-quality fuel filter is installed upstream of the fuel pump to protect it from contaminants. Replace the fuel filter according to its manufacturer's recommendations or more frequently in dusty or harsh environments.
Mounting Security: Periodically check that the fuel pump and its mounting brackets are securely fastened and free from excessive vibration.
Cleanliness: Keep the area around the fuel pump clean and free of debris.
Do not attempt to disassemble the fuel pump. There are no user-serviceable parts inside. Disassembly will void any warranty.
