Replacing Fuel Lines: 98' Ford Ranger Step-By-Step Guide

Changing the fuel lines on a 1998 Ford Ranger can be a challenging task. While some people suggest using vice grips or a flat-bladed screwdriver, others recommend getting the right tool for the job, such as a fuel line disconnect tool, to avoid any potential fuel leaks. The process involves relieving the fuel pressure, removing the old filter, and installing a new one. It is important to wear safety goggles and take precautions to avoid any accidents. Additionally, there are different sizes of fuel lines and AC hookups to consider, and seeking advice from online forums or experts can be helpful.

Disconnecting the fuel lines

Firstly, it is important to relieve the fuel pressure in the system. Locate the Fuel Inertia Switch under the glove box, on the passenger side of the transmission hump. Disconnect the wire connector using a small flathead screwdriver. Then, put your key in the ignition and crank the engine for 20-30 seconds.

Next, put on your safety goggles. You will need to crawl under the truck and locate the fuel filter. The filter is situated under the driver's frame rail, on the inside, roughly below the driver's seat.

Now, for the disconnecting process:

• Take note of the direction your existing filter is facing, so you can install the new one correctly.
• Remove the filter from the spring clips that hold it to the frame.
• Use a metal Quick Disconnect tool to remove the fuel lines from the filter. Place the two halves of the tool around the fuel filter tube and slide them into the fuel fitting. You may need to put one half in first, then the other, if there isn't enough space. Gently hit the tool with a hammer if it gets stuck.
• Hold the fuel line with pliers and pull the filter out while pressing the disconnect tool into the fitting.

You may lose about half a cup of fuel when you remove the filter, so be prepared to catch this with a container or cap from the new filter.

There are a few different tools you can use to disconnect the fuel lines. Some people suggest using a set of A/C tools or vice grips, but these may not be as effective or safe as a proper fuel line disconnect tool. You can purchase these tools from auto parts stores or online.

Remember to always take the necessary safety precautions when working on your vehicle, especially when dealing with the fuel system.

Relieving fuel pressure

To relieve the fuel pressure on a 1998 Ford Ranger, you must first find the Fuel Inertia Switch. This is located down by the panel your passengers might put their feet against, just under the glove box. It is about 1 inch square and has wires connected to the bottom. Use a small flathead screwdriver to disconnect the wire connector. Then, put your key in the ignition and crank the engine for 20-30 seconds. You will know you have found the switch when the engine does not start.

Removing the old filter

To remove the old fuel filter from your 1998 Ford Ranger, you will need to relieve the fuel pressure. Find the Fuel Inertia Switch under the glove box, disconnect the wire connector using a small flathead screwdriver, and crank the engine for 20-30 seconds.

Before you begin, it is important to put on safety goggles to protect your eyes from any fuel splash. It is also recommended to raise the front of the truck to prevent fuel siphoning.

The fuel filter is located under the driver's frame rail, on the inside, about where the seat is. To remove it, you will need to take off the spring retainer clips or retainer doohickies that hold the filter to the frame. You will also need to remove the springy things or retainer clips on the Quick Disconnect fittings. These can be released by squeezing and twisting them to release the tab and slot that holds them together.

Now, take your metal Quick Disconnect tool and put the two halves around the fuel filter tube. Slide them into the fuel fitting. If there isn't enough room, put one half in first, then the other. Slide them in as far as they can go; you may need to hit the tool lightly with a hammer if it gets stuck. Gently hold the fuel line with pliers and pull the filter out while pressing the disconnect tool into the fitting.

You might lose about half a cup of gas when the filter is unhooked, so be prepared to cap it with the caps from the new filter.

Installing the new filter

Now that you have successfully disconnected the fuel lines and removed the old filter, it is time to install the new one.

First, ensure that the new filter is facing the right way. The FRAM filter is marked with an arrow, but the NAPA filter is not, so be sure to pay attention to the direction the old filter was facing before you removed it.

Next, slide the filter tubes into the Quick Disconnect fittings. Once they are firmly in place, replace the spring retainer clips. Finally, snap the new filter back into the clip on the frame.

Now, you can test out the new filter. Put the key in the ignition, put it into the accessory position for a minute, then turn the key. If your truck doesn't start, remember that you unhooked the Fuel Inertia Switch! You will need to plug the switch back in. According to the Haynes manual, you might need to push the button on top of the switch, but this may not be necessary.

Testing the new filter

To test out the new filter, put the key in the ignition, and put it into the accessory position for a minute. Then, turn the key and start the engine. If you're like the writer, you'll wonder why the truck isn't starting, then remember you unhooked the Fuel Inertia Switch! You'll have to plug that switch back in. The Haynes manual says you might need to push the little button on top, but the writer didn't have to. Put the key in Accessory, and wait a minute. Then turn the key, and you're in business!

The writer figured their old filter was slightly clogged, because their truck ran a bit smoother now, especially at idle. At the very least, they could check off one dot on their maintenance list.
