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 efficiency. Featuring universal fitment, a built-in 7A self-resetting fuse, and 15 feet of wiring, it ensures easy installation and reliable operation for 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. ## 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 | |---------------|-------| | Brand | Revolution Electronics | | Fit Type | Universal Fit | | Vehicle Service Type | Car, Truck | | Material | Plastic | | Specification Met | OE | | Auto Part Position | Rear | | Body Material | Plastic | | Inlet Connection Type | Hose Barb | | Gas Type | Gasoline | | Mounting Type | Tank Mount | | Operation Mode | Electric, Mechanical | | Product Grade | New | | Manufacturer | Revolution Electronics | | Item Weight | 12.8 ounces | | Package Dimensions | 5 x 3 x 3 inches | | Is Discontinued By Manufacturer | No | | Manufacturer Part Number | 12003 | | Voltage | 12 Volts | ## 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 ### ⭐⭐⭐⭐⭐ 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. ### ⭐⭐⭐⭐⭐ Easy to install. Works as advertised. *by C***R on July 18, 2020* I used this to fix a problem with my ski boat. My 1994 Ski Nautique with a Ford 351 and Pro Tec ignition with TBI is notorious. It was the stepping stone between a Holly 4 barrel and port injection. They are super strong when working right but were problematic. They stopped making them after only one year, 1994 or 95 and stopped making parts. Once the ECU stops functioning you have to go all old school, strip off the ECU, coil, throttle body injectors, and go with a carburetor and distributor, and coil, and a new wiring harness, and new plug wires. My ECU stopped running the fuel pump. Everything else works. I could hot wire the relay to run the pump with the ignition switch on. But coast guard regulations, safety, and common sense require the fuel pump to turn off when the engine isn't running. With this switch I was able to get rid of my fuel pump relay, crimp on spade ends, and push them into the appropriate relay plug terminals, and ground the switch,following the schematic, all connectors provided except the spades. Now it works perfectly. It runs the pump for 3 seconds after turning on ignition, and it picks up the tach signal to turn on the pump while the engine is cranking and running. I was surprised the tach picks up enough signal to run the pump with just the starter cranking the engine over, but it does.Now my boat runs great and I can allow my family members to use it without unnecessary risk, at least until my ECU loses another function. So I saved having to buy $2500 worth of conversion kit to calibrator and distributor and a days work. Plus the old ECU does a nice job controlling the idle although it runs rich. I have power up the wazoo. The only thing is my tach sometimes drifts off. Like I know the idle is around 800 rpm but the tack sometimes reads 1100. I don't know if its the ECU, the tach, or this safety switch but I'm not all that worried about the tach accuracy. It does hold steady when pulling a skier. I find it easier to maintain a steady speed by watching the tach once I can see the rpm needed to hold that particular boat speed, and the tach is still working for that. I don't know that this switch is interned for marine use but the switch itself is sealed and it is under the engine hatch so as far as I'm concerned the safety it provides is the important thing. ### ⭐⭐⭐⭐⭐ Perfect for electric fuel pump conversions in classic cars. *by L***R on May 1, 2025* I’ve had this installed in my classic VW bus for quite awhile now. It works perfectly in place of the old, hard to find, and expensive VW “double relay”It runs the fuel pump for a few seconds when the key is turned on to pressure up the system…. Then it runs the pump ONLY when the engine is running. Which is exactly what you need when converting to electric fuel pumps or if your old double relay has gone bad.It’s simple to install, and takes no special skills. ## Frequently Bought Together - Revolution Electronics Electric Fuel Pump Controller.
