How do I replace the fuel filler neck of my Ford Ranger?

What can I do to replace my Ford Ranger's fuel filler neck? The check engine light was on, so I ran a quick diagnostic. I found that my fuel filler neck is rusted and needs replacing.

That’s a common problem with a Ford Ranger, especially if it’s on the older side. But be advised, replacing your fuel filler neck requires advanced mechanical experience, so it’s best to take it to a professional.
If you’ve fixed your fair share of cars in the past, then here’s what you need to replace a Ford Ranger’s fuel filler neck:
  • 7 mm and ⅚ inch sockets with ratchet and extension
  • Flathead screwdriver
  • Penetrating oil
  • Filler neck replacement
  • Begin by opening your gas tank and removing the three 7 mm screws surrounding the opening of your fuel tank.
  • Unscrew the connecting bolt that attaches the inner tube of your fuel tank to your filler neck. Use penetrating oil to ease the process if your filler neck is rusty.
  • Use the flathead screwdriver to detach the filler neck from the inner tube completely.
  • Place a clamp on the inner tube and put penetrating oil on the new filler neck. Turn the new filler neck into the inner tube and tighten it with a screwdriver.
  • Follow it up with the ⅚ inch sockets to secure it in place.
  • Place the neck back into its starting position and reattach its corresponding bolts. Don’t tighten all the bolts until they’re securely in place. Also, don’t forget to put back the tank’s cap while doing so.
There you have it! You’ve replaced your fuel filler neck.
