Revolution Electronics Electric Fuel Pump Controller. Primes the pump on key-on and turns the pump off if the engine stops.

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.

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.

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.

Wired it as instructed and it worked great!

I’m very pleased with the Revolution Electronics Electric Fuel Pump Controller. The installation was easy, and it worked perfectly right out of the box. It reliably regulates the fuel pump and provides consistent performance. I’ve had no issues with it, and it’s made a noticeable difference in my vehicle’s performance. Highly recommended if you’re looking for a dependable fuel pump controller.

I wasted a lot of money and time rigging up an electric fuel pump for my 63 tbird. I went through two pumps and eventually went back to mechanical because of the elec. pump noise. After all that, this product does what it says it will and the support is excellent. Staff emailed me back ON A SUNDAY because I had trouble wiring it through and existing relay - which I eventually just removed.

Great product, working well on my antique auto.

Bought this last year, only now got around to actually install it. Installation is easy, straightforward instructions. Works perfectly, as advertised. Unit will run pump for 3 seconds, when ignition is turned on, and keeps the pump running as soon as the engine runs and the unit receives the signal from the negative post of the ignition coil.
