guage wiring
 

i have 3 guages that go dead when i turn the dash lights on. 2 of them are the fuel guages. They have done this since fountain replaced the gas tanks. I am sure its a ground in the wrong place. Anyone know what wire is what? And my kill switch only kills one engine any ideas. I figured i would fix these issuse while the boat is apart.
