Revolution sells a great system - includes relay, a tach pulse sensor so it will stop fuel pump in the event the engine stops....plus it will run for 3 seconds when first engaged to help put fuel into carb for those starts after car has sat, fuel evaporated from the bowl. The safety features of sensing running engine is well worth it. The only negative was the power wire to electric pump when located at rear of car may need lengthening depending upon location of the controller. It’s $65 US. I located mine under dash, ran the pump power wire through the rear wiring harness, along the wiring harness in the trunk, had to lengthen this wire....no big deal.
That’s the relay system we installed on a Regal a few months ago and the one I’ll be using also. What I need is the best feed wire location I.e. fuse panel accessories (just an example ) location someone is using with good results
All you need is ignition on 12 volts to trigger the relay. The main feed wire for the pump should come directly from the battery.
I hooked one up years ago to a rear defroster switch on a '70. Good theft deterrent also, who's gonna think to turn on a rear defrost switch to activate pump.
All the factory systems controlling electric fuel pumps, will cut off the pump shortly after the engine stops turning even with the ign on. The reason is in case an accident breaks a fuel line, the pump will not empty the entire tank onto the ground and probably cause a massive fire. There are many ways to do this, sounds like Revolution has come up with one. Bruce Roe
Several ways to skin this cat. (for other's looking for options/ideas) This is how I wired mine on my '64 Skylark. Uses an Oil pressure switch to shut off pump at 3-9 PSI. Feed is from the horn relay 10AWG along the body (parallel in case one of the relays fails. test when I do oil change by disconnecting one relay at a time) I also have a momentary switch to prime if the car sits for a few days so it does not crank until oil pressure triggers the switch, and it fires off more quickly.
