Thankfully we have no goofy surfers in our crew, so I only need to increase water flow to the rear 1100# bag. I want to use the original rule pump to fill the front bag and the bag that replaced the cooler. I would like to install a tsunami 1200 to fill the 1100# bag.I get the mechanical side of the install, but need help with the electrical so that the fill switch will only run the new pump and not the rule pump. Thanks in advance for any help and advice.
