Default help with fuel pump wireing

Using a stock avalanche pump in my conversion, it hes grey,black, purple,black. What is what? Guessing the black are ground, can they be combined? Do I need any other ground? Thanks.

grey is pump power, heavy gauge black is pump ground, purple is gauge and other black is gauge ground and for accuracy should go to a pcm ground
