I am considering drilling my sump to place a 1" bulk head. what diameter do I need to drill the hole?

Depending on the bulkead you are buying. Most will require a 1-3/4" hole.

It depends on the bulkhead. Buy your bulkheads and measure each before drilling to be sure.

Definately buy the bulkhead first. Hole size will depend on the manufacturer of the bulkhead, and the material it is made of.
