Revolution Electronics Electric Fuel Pump Controller
The Revolution Electronics unit primes the fuel system for a few seconds on key-on and immediately shuts the pump off if the engine stops. It monitors a tach signal to keep the pump active only when the engine runs, making it ideal for classic cars with either stock inductive tach or aftermarket square-wave tach signals. It is suitable for vehicles upgraded from mechanical pumps and for engines without a tach by wiring to a coil’s negative side. Best for enthusiasts who want automatic priming and engine-synchronized fuel delivery, with a simple installation path.
- Best for vehicles with tach signals and priming needs
- Better for classic cars needing automatic pump control
Caution: Ensure tach input wiring matches your engine type to avoid improper pump operation. Data indicates it primes on key-on for a few seconds and stops when the engine stops.
