Here's a pic of how I set up my feed. I'm running a mag 12 with 1" tubing as well. The 1/4 NPT tap is cheap and can be used for other projects. The line is 1/4" OD and the valve is for a underground sprinkler system(bought at Homedepot). There is some risk of cracking the pvc when you tap it so be carefull and/or have some weldon 16 handy.
