Question about replacing fuel lines

[PJ Grady Inc.]

Oh, and one more thing: I was reassembling everything at night with a work light last night. I couldn't get the air filter assemble to seat properly. Come to find out, I had caught something and ended up breaking it off. That's what I get for not being careful and just wanting to get it put back together so I could go to bed. I don't recall what this thing is called and what function it serves. Is it fine to leave it broken like that, or do I need to replace it?

That is a CO plug tool that you broke free from the rubber. As long as the rubber plug you can see in the picture is still secure then your OK. Don't bother reinserting it in the rubber plug as it will just fall out eventually and could cause some unforeseen issue if it lands in the wrong spot. Murphy's law dictates that it will!

Sounds good. The rubber plug is secure, so I'll move on to the next issue causing me to lose sleep at night: the possibility that not all my new fuel lines are 100% leak free. Any additional tips are appreciated.
