Not sure this is the correct place to put this. But I'm installing the radium duel fuel pump kit. Running 2 450s. I have 2 rewire kits. I've read several articles and didn't see a answer. I like the hobbs switch to the ignition. My question is, with duel pumps and rewire. Do I run 2 hobbs switches or one? In theory I would assume 2. But would like to be sure. And if 2 are required is that safe to run 2 on the ignition on/off wire?
