So I cracked the hose that drains the filter housing. I want to make sure I know what is what. I found the following diagram: https://www.google.com/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0ahUKEwjh88S63p_RAhVBKiYKHQZsAroQjRwIBw&url=http%3A%2F%2Fwww.dieselplace.com%2Fforum%2F63-gm-diesel-engines%2F21-6-5l-diesel-engine%2F709937-fuel-filter-fuel-flow-diagram.html&psig=AFQjCNE-vvkMf1OvFyp3S7FIzaoyk_PhOA&ust=1483317599825830

There seems to be a missing piece and the pieces aren't labeled.

There should be an inlet, outlet and the drain line. I am thinking the 90 degree port on the diagram is the drain. What size line is this? Is the 90 degree port the drain for sure? Does anyone have a better picture?

Thanks!

Is this for a 6.5TD (the forum you’re in) or a Duramax (the one in your signature)?
