ALB, Im going to put 3 or 4 strips of high density plastic the length of the tank 3/8" x 1"x 60". 5200 them directly to the underside of the tank while it is out and let dry, making sure it is completly sealed to prevent water from getting under it. Then 4200 the tank in place appying a good bead to the3 or 4 plastic strips with a helper put in place and let dry this should be all you need to hold tank inand it will let air circulateall around the tank this is how SP tanks recomends that you install marine fuel tanks take alook at SPmetals.com
