The 2213 has 12/16 outflows. That means the inside diameter is 12mm. You would use a 13mm or 1/2 inch pipe.
On the 2217, it has two difference sizes. One is the same as the 2213, 12/16. However, the inflow tubing is bigger, so you would need a 17mm or 5/8in lily pipe. I would check those numbers, but I know the 2217 has 2 different sized tubing.
It's not hard to buy high end lily pipes in 2 different sizes but cheap ones are unfortunately sold in sets.
