So I've read lots of threads about installing an electric fuel pump in place of the mechanical pump as well as using the electric pump just for cold starting if the vehicle (truck in my case) has been sitting for awhile. The consensus seems to be not to run an electric fuel pump while also using the mechanical fuel pump. I have also been told running the two together would not be an issue but many comments seem to oppose this.
What I would like to do and maybe others have done this as well but I haven't read anything about it is I would like to install a toggle switch for the electric fuel pump but have it powered by the ignition switch. So the toggle switch would only have power when I turn the key in the ignition and even when there is power from the ignition I can turn off the electric pump with the added switch. This would ensure that even if I forgot to turn off the electric pump it would not run once I turned off the truck, thus making sure I didn't flood the carbs by accident. Does this make sense? Or maybe this is how everyone wires their switches?
