Sump for AGA 210 with Predrilled Overflows

i would just follow the instructions the company suggests.
 
I went with 2 3/4" bulkheads and 2 1" bulkheads from www.savko.com.

They are parts 501007 and 501010. This way I can hard plumb the return line and potentially the drain as well. I got the slip slip variety.
