Here's what you'll need to do:
* Choose a suitable pump: Select an external fuel pump with the appropriate flow rate and pressure for your engine. Make sure it's designed for gasoline and has the correct fittings.
* Location: You'll need to find a secure and protected location for the external pump. Somewhere near the fuel tank, but shielded from road debris and heat is ideal.
* Wiring: You'll need to run new wiring from the pump to a power source (usually a switched 12V source, possibly through a relay for better protection). Properly sized wiring is crucial to avoid overheating and potential fire hazards.
* Fuel Lines: You'll need to connect the external pump into the fuel line *before* it reaches the engine. This often involves adding new fuel lines and possibly using fuel line clamps and connectors. Make sure your connections are leak-proof.
* Pressure Regulator (Possibly): Depending on the pump you choose, you might need a fuel pressure regulator to prevent excessive fuel pressure to the injectors. Check your pump's specifications.
* Filter: A fuel filter should be installed near the pump's inlet to protect it from debris.
Important Considerations:
* Safety: Gasoline is extremely flammable. Work in a well-ventilated area, away from open flames and sparks. Use proper safety equipment, including eye protection and gloves.
* Fuel Line Routing: Plan your fuel line routing carefully to avoid sharp bends or kinks that can restrict fuel flow.
* Grounding: Ensure the pump is properly grounded to prevent electrical problems.
* Professional Installation: If you're not comfortable working with fuel systems, it's highly recommended to have a qualified mechanic install the external fuel pump. Improper installation can lead to fuel leaks, fire hazards, and engine damage.
This setup will have the internal pump and the external pump working together. This can increase fuel delivery, especially beneficial for modified engines or if the in-tank pump is showing signs of age. However, remember this adds complexity to your fuel system, and regular maintenance is even more crucial.
