Factors increasing difficulty:
* Tank Access: You'll need to drop the fuel tank, which involves disconnecting fuel lines, electrical connectors, and possibly the tank straps. This is the most time-consuming and potentially messy part.
* Fuel System Safety: Working with gasoline is dangerous. You must take precautions to prevent sparks and fires. This includes disconnecting the battery, allowing pressure to release from the fuel lines, and working in a well-ventilated area.
* Potential for Leaks: There's a risk of leaking fuel during the process if you're not careful when disconnecting and reconnecting fuel lines.
* Tight Spaces: Working under the vehicle and around the fuel tank can be cramped and awkward.
* Special Tools: You may need specialized tools, like a fuel line disconnect tool, to avoid damaging the lines. A fuel pump access tool can also be helpful, but not always necessary.
Factors potentially making it easier:
* Experience: If you have prior experience working on vehicles, particularly with fuel systems, it will be significantly easier.
* Good Repair Manual: A good repair manual with clear diagrams and instructions is essential.
* Right Tools: Having the right tools will speed up the process and reduce frustration.
* Access to a Lift: Working on a lift will greatly improve access and make the job safer and easier.
In summary: While not impossible for a determined DIYer, replacing a fuel pump in a 2004 Ford Ranger requires patience, the right tools, a safe work environment, and a basic understanding of automotive repair. If you're uncomfortable with any aspect of this, it's strongly recommended to have a qualified mechanic do it. The cost of a professional repair might be worth avoiding the risk of fuel leaks, fire, or injury.
