2003 Explorer P0171, P0174 codes

Hello,

2003 Ford Explorer, with P0171 and P0174 codes, common problem, as I have read. I pulled the cover over the engine off, and I immediately found the likely problem. There is a hose/connection that runs from the valve cover on the right side, about 6 inches behind the oil fill tube across and looks like it comes into the Carb. Where it turns to come into the carb is a rubber elbow. This elbow has a hole in it. Temporarily I have used electrical tape, but when I run the vehicle, I see the elbow begin to collapse. I believe the elbow is getting weak with age, plus the hole/tear doesn't help. Anyway, does anyone know of the part number, or what this is called. Hoping Advance Auto, or Napa will have it, just don't know what it is called, and can't figure out the part number.

Any assistance is appreciated. Otherwise I will pull it off tomorrow and take to advance and see if they can match it.

Thank you

Andrew

Sorry, of course, valid supporting information would help

4.6 engine. I am not certain on the carb.

I believe the question on the carb is because you used the term "carb" in your post, and almost no new cars since 1986 used carburetors. Your Explorer is certainly fuel injected. But, I suspect you mean the "throttle body" when you typed "carb".
