It primes the pump for 3 seconds on key-on, then monitors the engine's tach signal to run the pump only when the engine is active, enhancing safety and preventing fuel flooding. Compatible with various tach signals and includes a self-resetting fuse and 15 feet of wiring for easy installation on 12V cars and trucks. ## Description Designed to safely control an electric fuel pump when a classic vehicle is upgraded from a mechanical fuel pump to an electric fuel pump. Powers the pump for three seconds on initial power-on to fill the carburetor bowls. After those first three seconds, the pump will only run if there is a tach signal. If the tach signal stops, the pump shuts off. Includes an internal 7A self-resetting fuse, 15 feet of 16 gauge wire, and the necessary hardware for most installations. Review: Perfect for Custom Sandrails with Electronic Ignition - I’m running this controller on an air-cooled VW sandrail with an upgraded electronic ignition (Magnaspark II) and a 3 psi pump with an electric fuel solenoid. Out of the box, the unit was staying on steadily, but the instructions and the seller’s quick response pointed me exactly where I needed to go. Because of the high-energy ignition and the solenoid, my system was a bit "noisy" electrically. Following Figure 1 in the manual, I installed a diode across the pump/solenoid (Stripe to Positive, Tail to Ground), and it completely fixed the issue. It now primes for 3 seconds and shuts off perfectly as it should. Very happy with the product—it’s a simple, effective safety feature for any custom build. If you're running a high-output coil or solenoids, just grab the diode as the instructions suggest and you'll be good to go. Five stars for the quick customer support! Review: Great solution - I have purchased probably 6 of the Revolution controllers. I restore/collect Corvairs that have a mechanical fuel pump which is best removed and replaced with electric fuel pump.. These controllers provide a solid safety solution for operation of the pump to prevent hydra-lock with continuous pump operation and prevention of continued pump operation in event of an accident. The Revolution controller can be wired to operate in concert with an inertia switch to provide a complete safety solution. ## Features - Monitors the tach signal - as long as there is a tach signal present, the pump is allowed to operate. If the engine stops, so does the fuel pump. Works with both inductive (stock) and square-wave (aftermarket) tach signals. For vehicles without a tach, connect to the negative side of the coil. - Turns on an electric fuel pump for 3 seconds on initial key-on. This primes the fuel system and tops off the carburetor's fuel bowls. - Controls an electric fuel pump when a classic car or truck is upgraded from a mechanical fuel pump. - Includes an internal self-resetting 7 amp fuse and 15 feet of 16 gauge wire to connect the fuel pump. Higher amperage pumps can be controlled by adding an external relay. - For 12V vehicles. 2 by 1.5 by 1 inches. Fully potted. - Made in USA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BNZ05JM | | Auto Part Position | Rear | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #232,167 in Automotive ( See Top 100 in Automotive ) #1,250 in Automotive Replacement Electric Fuel Pumps | | Body Material | Plastic | | Brand | Revolution Electronics | | Brand Name | Revolution Electronics | | Compatible with Vehicle Type | Car, Truck | | Connector Type | Hose Barb | | Customer Reviews | 4.7 out of 5 stars 173 Reviews | | Fit Type | Universal Fit | | Gas Type | Gasoline | | Hose Length | 15 Feet | | Inlet Connection Type | Hose Barb | | Manufacturer | Revolution Electronics | | Manufacturer Part Number | 12003 | | Material | Plastic | | Material Type | Plastic | | Mounting Type | Tank Mount | | Operation Mode | Electric, Mechanical | | Outlet Connection Type | Barb | | Product Grade | New | | Product Style | Electronic | | Specification Met | OE | | Style | Electronic | | Unit Count | 1.0 Count | | Vehicle Service Type | Car, Truck | ## Product Details - **Brand:** Revolution Electronics - **Fit Type:** Universal Fit - **Vehicle Service Type:** Car, Truck - **Material:** Plastic - **Specification Met:** OE ## Images ![Revolution Electronics Electric Fuel Pump Controller.

We charge our cost to ship (nothing extra added on). **Q: Are the instruction/wiring diagram online somewhere?** A: The Wiring diagram instructions for # 12003 Revolution /// electronics **Q: Hello i purchase despicable pump and i need a new daoud where can i get one** A: The diode in our kit is a 1N4001 General Purpose diode. These are very very common and inexpensive. You should be able to source one locally any place where electronic components are sold. **Q: Is it possible to connect both this device and my tach to my msd ignition box? would that configuration function?** A: Yes, that should work fine. That is how I have my personal car setup and have no issues. Controller works great and tach works great. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for Custom Sandrails with Electronic Ignition *by D***L on March 25, 2026* I’m running this controller on an air-cooled VW sandrail with an upgraded electronic ignition (Magnaspark II) and a 3 psi pump with an electric fuel solenoid.

These controllers provide a solid safety solution for operation of the pump to prevent hydra-lock with continuous pump operation and prevention of continued pump operation in event of an accident. The Revolution controller can be wired to operate in concert with an inertia switch to provide a complete safety solution. ### ⭐⭐⭐⭐⭐ A wonderful modern solution to an age old problem *by D***N on August 8, 2023* I bought this controller for use on my 1963 Corvair Greenbrier van that I had switched over to an electric fuel pump. The included instructions were clear and made connecting it a pretty simple task. I was able to hook everything up in the engine bay (minus the wires I ran to the pump it self.) With this setup, the system primes it self, and turns the pump off any time the engine isn't running. This is a much better option than the oil pressure / inertia detector / dash toggle switches that folks have used over the years in Corvairs (and other vehicles converted from a mechanical pump). It's a neater solution, and much safer overall. This controller would also be an excellent "solid state" fuel pump relay replacement for fuel injection cars of the 70s and 80s. I give this product my highest recommendation. ## Frequently Bought Together - Revolution Electronics Electric Fuel Pump Controller.
