What is this?

2005 Tahoe Z71
It runs and drives like a champ but sometimes while idling it will cut off but I can crank it right back up...only 2 codes Im getting is for evap solenoid and o2 sensors, but while looking under my truck for the solenoid I found that I have a couple of chopped lines but I dont know what they are...any help? Thanks in advance

Looks like evap hoses not hooked to something that is missing.

Welcome to the forum from Oregon. I have a 2005 Z71 too. Post pics please. I also agree with @89Suburban.

I had a bank 1 sensor 2 code and had a bad oxygen sensor. Did all 4 sensors and runs like a top.

Mileage?

275xxx miles on her and yea those codes popped up today as well as the p0449, no wonder it came back up...looking deeper into the issue it seems like I may need a fuel pump too smh

Any idea of what it could be?

looks like someone cut the two lines instead of just disconnecting them, you might be able to patch them back together

Problem solved it was the fuel pump as I thought, those hoses all went to the evap canister so I grabbed some off another truck and attached em, she runs like a champ now

I will see the pics but this statement is confusing to me. How was it determined that it is a fuel pump problem? The fuel pump is not what is missing in that pic. You said you got a used evap cannister and installed it where the hoses were in the pic, right? Then you said it runs like a champ. Now you say it has a bad fuel pump. Sorry, but I am confused.
