You just need the flat gasket p/n 23135703.

I did the gasket but could never find the part # for the o-rings on the line. They seemed to be in good shape so I just reused them and have had no issues. Or rather no issues once I made sure both o-rings were on the lines before reinstalling but that's a whole other issue...
