Ray and all, What started out as relatively simple is getting confusing because of different years and switch types. The way I have my G elec fuel pump wired is the way Ray describes, a wire from the "on" terminal to the pushbutton then to the pump and then to ground to complete the circuit. What Bruce is doing is connecting the pump to the "start" output from the key switch, where it connects to the starter relay. When the key switch is turned to "start", voltage is applied to the elec pump and it is then energized. To keep the starter from turning over, he depresses the trans selector button to any position BUT Neutral while he is pumping up the fuel. This way the neutral safety switch keeps the starter relay from closing because there is no ground present. Once the fuel is pumped up, press the Neutral button, turn the key, and it fires right up. Please note, this only will work on later cars that use the ignition key to start the motor, NOT the Neutral pushbutton. I'm not sure what years use the Neutral button for starting, but I think it is '55-'57, someone can correct me here. As far as using both a pushbutton and a connection to the starter relay, I don't recommend it because if you pushed the fuel pump switch button with the car in Neutral it would close the starter relay and turn over the engine at the same time, and if the engine is running, that would not be a good thing. So, the point here is to use one or the other, but not both. What Ray is describing is having both a toggle switch AND a separate pushbutton, yet another way to do it, but in my opinion unnecessary because the only time you would need the toggle is if the mechanical pump fails. Sorry for all the confusion, but installing the electric fuel pump really is the answer to hard starting after the car sits for an extended period. I just hope you all aren't tired of the subject and my postings!

You don't want to use the "Start" circuit at all. Use the "ON" side of the Ing. switch, and from there to both switches. From both switches to the pump. Actually, it only takes one wire on either leg. From the Ing. switch "ON" to the momentary button, with a jumper to the toggle switch. That supplies power to both. Out of the push button to the "OUT' side of the Toggle and then to the pump. This way it will only work with the ing. switch ON, and using either button or toggle will send current ONLY to the pump as the other switch is not used and leaves an open in the circuit. Turn your Ing. switch on, push the button until it stops "ticking" and then start. If the mechanical pump quits, flip the toggle, and use the Elec. Pump to get ya home. And when you turn off the Ing. switch, the pump's off even it you forget to switch the toggle off. Hope that's clear without a diagram.

I think I'll just stick with one switch controlling the pump, either the starter solenoid or the separate pushbutton, but not both.
