Installing the Flow Charger is straight forward, and the unit can be mounted anywhere, since it is simply wired in place and not an actual part of the fuel system. We installed ours in the trunk compartment of our Challenger, in the lower area near the battery, which made much of the wiring easy. If you can perform simple wiring and mechanical tasks, installing the Flow Charger is easy to do yourself, and much less involved than removing and replacing the factory fuel pump. Other than wiring the unit into the electrical system, the only additional modification is to replace the 20-amp fuel pump fuse (number six fuse in the rear power distribution center) with the supplied 30-amp fuse.

After installation, we didn't really notice any difference in fuel pressure, but did notice that fuel pressure seemed to remain more constant at full throttle. Testing voltage at the unit with a volt meter, we saw the voltage increase when the boost pressure switch was activated. Without a fuel flow meter, it's hard to tell exactly how much more fuel the pump is providing, but we did improvise a test of our own using a stop watch and gas can.

Tapping into the fuel line and with the engine not running, we turned the ignition on and used a stopwatch to measure how long it took to fill a one gallon gas can both with and without the Flow Charger engaged. Granted this was not an entirely scientific test, but we did see that with the voltage boosted to 16.5 volts by the Flow Charger, it took approximately 30 percent less time to fill the one gallon gas can, equating to a 30 percent increase in fuel flow. So if you want more fuel to your late-model Hemi without dousing yourself in gas, the Flow Charger from Easy Performance is a great option.
