Bulkhead size

[sergifed91]

I measured my bulkhead hole to my sump. But since I'm not very good at determining the size and measurements I need some help. I was trying to follow BRS chart on bulkheads but I need some assistance. See pic below. I thought 1 inch but I tried a one inch bulkhead and just small.

Ty. I'll order an inch and a half if in reading it correctly.
