Which Facet fuel pump? They make several.
The most common is the small rectangular unit with pulsed fuel delivery, These are low cost, work OK. The produce fuel to the carb in pulsed burst which can cause problems by essentially bouncing the float valve due to the pulsed fuel delivery. Put enough hose or fuel container after this pump to smooth out these pulses. Fuel pressure delivered not always predictable No a a favored pump.
Facet also makes a cylindrical ticker pump with a strainer built in on the bottom. These began life as a Bendix pump, eventually the design was sold and still made by Facet. There are several version from low pressure about 2-3 psi, 12Volts nominal which is the one to use a higher variants that produce fuel pressure above 4 psi and 24 volt variants used in small piston engine aircraft and boats. Favor this pump as has a proven record of reliability and durability in cars, small aircraft and boats.
Carter makes a rotary vane fuel pump, these work good too. They tend to have smooth fuel delivery with minimal pulses. This pump requires a pressure regulator as the spec pump pressure is 4 psi and up.
In all cases do add an inertia switch to stop fuel flow in case of a crash. There are a number of them available, we used a OEM FORD inertia switch.

As for powering the pump, depends on the specific year of exxe. Basically it should be ignition switch power in the running position. Do add it's own fuse rather than stealing power from another circuit. This allows diagnostics to be done and reduces wiring confusion in many ways.
Do add a fuel filter post fuel pump. Adding a fuel pressure regulator with fuel return is a good thing.

Greetings, at the risk of hijacking the thread, I am considering adding an electric Facet fuel pump to my carb' X. Does anyone have a recommendation where to connect the wiring? Which fuse/run wiring directly tp the fuse panel/is there an alternative power supply within the engine bay?
Thank you.
