Can anyone tell me what these are for and can I ditch em? I’m goin with a carburetor stick shift sbc. Pulled the ecm? The renix Mosul but it connects to here and I don’t wanna chunk anything I may need. Also will ditch the electronic fuel pump. Only creature comfort is ac. Otherwise everything is mechanical. Manuel windows locks tranny ect. I have a Haynes somewhere but not sure where and don’t wanna buy another. Thanks in advance!

4.0s do not have a provision for a mechanical fuel pump. What are you going to do for a fuel pump if you ditch the electric? It would likely have to be another electric one that's lower pressure.

Is this a 2.5L? Poster needs a signature with vehicle information.

That bracket would make this an early 86 2.5L

It was. The bracket on the pass side fender well is a great indicator of such.
