Manifold tubes?

I am installing headers and I noticed there was a tube that goes in the back of the driver side manifold. What is it for and can I delete it?

It would also help to know what truck you're working on(F150, F250, etc), the year, and what engine.

Anybody? My new headers do not let me put it in. What happens if I drive it without the tube hooked up?

EGR TUBE

It looks like you reside in Texas, so I do not know what your state inspection laws are like, but if you delete the EGR portion of the emissions controls you could be in violation of local or state ordinances. I know there are headers for that model truck that do have a provision for the EGR tube, you may want to find a set of those. The EGR is exhaust gas recirculation, and it is used to reduce emissions, I believe Oxides of Nitrogen. If you do not use the EGR, I think you will find you have some pinging issues that you will hear on acceleration, if you live where there are no hills to climb, you may be able to add higher octane fuel to avoid the pinging maybe not. Good luck on your project! Dale

The problem is not that it doesn't havr a bung for it. The bung on it is fine thread, the tube is standard thread

Tye, who manufactured these headers? I think if they were say Doug Thorley or Hooker, they woul have provided an adapter to make it possible to hook up the OEM EGR tube. Dale

If you got a picture of the tube you were talking about we would be able to help much easier. As of now we are just guessing...

Sounds to me like you need the EGR connector fitting (Ford Part# FOTZ-9F485-A)
