It’s supposed to go to a fuel rail bolt that was removed when someone installed that dorman intake manifold and threw away the stock hardware. If I could make a recommendation, get rid of that intake and get a factory Ford intake.

Getting rid of it and replacing it isn't practical for me. I quick search explains that it's a ground wire. I guess just figure out somewhere to ground it to?

You could put a ring terminal on the end of the wire and put it under that bolt that holds the fuel rail down.

Ah, So I'd have to cut the wire. That kinda worries me, I'd be worried I'd screw something up.


Is it something that NEEDS to be done. It's be running for year without it grounded

I don’t really remember what that wire is for. However, there isn’t really anything you can mess up if you just cut it off and crimp a new end on it. Maybe Burns will chime in and let us know what this wire is for.

Are we interested in knowing what the wire is for or where it goes?

The wire is a ground wire. The purpose is to ground the fuel rail to prevent the build up of static electricity from the flow of fuel inside the fuel rails. By grounding the metal of the fuel rails this keeps the electrical potential at the same level as ground, there's no electrical potential difference that might cause a spark. The separate ground wire is needed because the intake is made of plastic. This makes the metal of the fuel rail electrically isolated from the engine block.

Where the wire goes is to one of the double sided studs that hold the fuel rail down.

Thank you Burns! I knew it was a ground to the fuel rail, but didn’t know what it was for. You never disappoint.
