Can I install an electric fuel pump on a carbureted 1985 Chevrolet pickup truck?

Yes, you can install an electric fuel pump on a carbureted 1985 Chevrolet pickup truck, but it requires more than just bolting one in. You'll need to consider several factors:

* Fuel Pressure Regulator: A carburetor needs much lower fuel pressure than fuel injection. An electric fuel pump will typically deliver much higher pressure than a carburetor can handle. You'll absolutely need a fuel pressure regulator to reduce the pressure to the correct level for your carburetor (usually around 5-7 PSI).

* Pump Location: Electric fuel pumps can be mounted in various locations, but you'll need to consider accessibility for maintenance and avoiding heat sources (like the exhaust manifold). A common location is near the fuel tank.

* Wiring: You'll need to wire the pump to a switched power source (so it only runs when the ignition is on) and ground it properly. An inline fuse is also crucial for safety.

* Fuel Line Modifications: You may need to modify or replace existing fuel lines to accommodate the new pump location and pressure regulator.

* Pump Selection: Choose a pump with the correct flow rate for your engine. A pump that's too small won't deliver enough fuel, and one that's too large might be inefficient and put unnecessary stress on the system.

* Return Line: Most electric fuel pumps require a return line to the tank. Your existing system may or may not already have one. If not, you'll need to add one to prevent excessive pressure build-up.

In short, while it's possible, it's not a simple bolt-on job. It's a more involved modification that requires some mechanical aptitude and understanding of fuel systems. If you're not comfortable working with fuel systems, it's best to have a qualified mechanic perform the installation. Incorrect installation could lead to fuel leaks, engine damage, or even fire.
