LARIAT 85 Posted December 19, 2022 Share Posted December 19, 2022 I'm in the same boat. My truck is running rough when I first start it in the winter. It shuts down every time I stop at a stop sign for the first 10 minutes of driving. Makes getting out of my neighborhood a little dicy at times! Do you think fixing this will help that? Yes, it will absolutely help! In fact, it should eliminate the problem completely. When you get the air tubes hooked up and the choke adjusted correctly, there should be very little difference between driving a carbureted vehicle in the winter compared to a modern fuel injected vehicle. (Yes, I am serious.) Wouldn't that be nice? Here is a diagram you asked for. This is for a V8 engine, but the setup is basically the same.

Powerman5K Posted January 5, 2023 Author Share Posted January 5, 2023 I have bought everything I need to replace this tube over the weekend. Has anyone ever done it without removing the manifold on a 4.9? I would rather not tear all of that out if it is not needed. I keep hearing horror stories about breaking off studs.
