Next you drill pilot holes for all the other holes on the mounting bracket. These holes will be used to screw the pump to this black bracket.
The pilot holes get enlarged to 1/2 holes to clear the nuts and washers. This makes it so the pump, control box, and filter are a unit held together separate from the forward plate.
Becareful not to turn the screws to hard. I cracked the plastic wire holder. But a little super glue and washers will work just fine to hold it.
