I see, so I guess I will be picking up a hobs switch. I will be using a '98 fuel pump assembly modified with dual walbro pumps in my '97 tank (LT1 car), LS1 fuel lines to the front to my LS3 fuel rail and 60# injectors.

Just be sure to monitor fuel pressure, my hobbs switch wouldnt turn on all the time, so i ended up bypassing it with a simple on/off switch. its crude but i know that it works

I have a fuel pressure gauge (not that I am sure to cautch a problem before it is too late). A switch is not a bad idea actually. I can leave one pump on for normal use, and switch on the second for when I hot dog it around. But I do like the idea of a hobs switch better. I could simply wire up a diode to it and have it light up when the switch closes so that I know it's on.
