Found out the usual way, but at least I know when it's running. Choose your mount carefully and try it for noise before you button it all up. Relay power from alternator with override switch and indicator light is the way to go.
Terry,
There is concern about the pump noise, but this coach is a 23 so the auxiliary tank is real close to the torsion bar cross member and that leaves little room to much other than mount them to the floor that I can see. There is an owner had mounted his fuel pump system on a hinged piece of aluminum that can be lowered. I really wanted to do that too, but there just is not room where they have to be in this coach. There was a plan to mount them outside the frame rail, but my parking brake worked recently and I want to get it back.
In my original plan, I had a delay circuit to run the fuel pumps on the starter, but I don't have the time in this program to include that.
Thanks to all
Matt
