Im in the process of redoing my fuel system. I am doing 8an feed and 6an return. the fuel pump is an external holley double pumper.
Question is what psi to turn the second pump on at. should I just use an adjustable pressure switch so I can change the turn on point or just get a set psi hobbs switch and stick with it. what pressure?
I will be trying running e85 mostly but am running 93/alky now.
