Answer
Thank you for your interest in Sump Pumps Direct.
Per Bur-Cam:
The inlet holes on the tank are not pre-drilled, they are made by the customer as per the location of their fixtures. Our image just shows them on one side as an example. Depending on the size, location, and severity of the crack, it is sometimes possible to cut a small piece from the edge of the lid and melt it, letting it drop on to the crack to fix it (for small cracks only).
If you have any other questions, please let me know.
