Replacing Fuel Lines: A Step-By-Step Guide For Your Jeep 304

Changing the fuel lines on a 304 Jeep is a complex task that requires careful attention to detail. Online forums and video tutorials can provide step-by-step guidance on how to remove and replace fuel lines, with some sources offering visual aids and diagrams for additional clarity. It is important to note that different Jeep models may have unique fuel line configurations, so ensuring that instructions specific to the 304 model are followed is crucial. This process may also involve working with various Jeep components, such as the carburetor, intake manifold, and fuel filter, making it a challenging but rewarding project for Jeep enthusiasts.

Removing the old fuel lines

To remove the old fuel lines from your 304 Jeep, you will need to first drop the tank. This will require some effort and focus, as described by a Jeep owner on Jeep-CJ.com. Once the tank is removed, it is recommended to also pull out the pick-up and sender to inspect the tank and check if it needs cleaning. This is also an opportunity to inspect the pick-up screen, which may need replacement, especially if it is made of plastic.

After inspecting and cleaning the tank, you can begin the process of removing the old fuel lines. It is suggested to have the new lines ready for comparison and to use a tubing bender if needed. The body/tub may need to be removed or loosened to access the mounting points for the fuel lines. This will involve removing or loosening the bolts on the right-side center area and possibly the mounts on that side to access the rubber and inner metal sleeve of the fuel lines.

The process of removing the old fuel lines may vary depending on the specific model and year of your 304 Jeep, so it is recommended to refer to a repair manual or seek advice from Jeep enthusiasts or mechanics with experience in this area.

Buying replacement fuel lines

When buying replacement fuel lines for your 1976 CJ7, 304 V8 Jeep, there are a few things to consider. Firstly, you'll want to ensure that the fuel lines are compatible with your Jeep's specific make and model. In your case, you'll be looking for fuel lines that fit a 1976 CJ7, 304 V8 engine.

You can find replacement fuel lines for your Jeep on websites such as Amazon or specialist automotive websites like inlinetube.com. When purchasing, it's important to check the product specifications to ensure the fuel lines are compatible with your Jeep's engine and fuel system.

Some replacement fuel lines come as part of a kit, which may include additional components such as hoses, clamps, and tubing benders. These kits can be helpful if you need multiple parts to complete the repair. It's also worth checking the reviews for these products to see what other buyers' experiences have been.

When choosing replacement fuel lines, you may also want to consider the material they are made of. For example, you can find fuel lines made from steel, nylon, or rubber. Each material has its own advantages and disadvantages in terms of durability, flexibility, and corrosion resistance.

Finally, it's important to compare prices and shipping times between different vendors to ensure you're getting the best deal. Some vendors may offer discounts or coupons, so be sure to look out for those as well.

By considering these factors, you can make an informed decision when purchasing replacement fuel lines for your 1976 CJ7, 304 V8 Jeep.

Rerouting the fuel lines

To reroute the fuel lines of a 304 Jeep, you will need to purchase a tubing bender and steel replacements for the fuel lines. You should also check the tank for any debris and ensure the pick-up screen is still in place.

Begin by removing the old fuel lines. Then, pull out the two body tub bolts on the right-side centre area and try to slide the new lines in from the rear (where the gas tank is located). You may need to loosen all the mounts on that side to get the rubber and inner metal sleeve out.

Alternatively, you can try to reroute the lines from the front. However, this may be more difficult with the tub still on.

When installing the new lines, be sure to use straps and clamps to secure them in place.

Installing a fuel filter

Step 1: Purchase the Correct Fuel Filter

Before you begin, make sure you have the correct fuel filter for your Jeep. The fuel filter you need will depend on the model of your Jeep and the type of fuel system it uses. In the case of the 304 Jeep, the fuel filter typically has two lines on one end and one line on the other. This is an important detail to ensure the proper functioning of the fuel system.

Step 2: Gather Tools and Materials

You will need a few tools and materials to complete the installation process. These include:

• A new fuel filter
• Wrenches or pliers to loosen and tighten connections
• A tubing bender, if needed, to shape the fuel lines
• Straps and clamps to secure the fuel lines
• A catch pan to collect any spilled fuel
• Gloves and safety goggles for protection

Step 3: Locate the Fuel Filter

The fuel filter is usually located along the fuel line, which runs from the fuel tank to the engine. In some Jeep models, the fuel filter may be found near the engine, while in others, it could be closer to the fuel tank. Refer to your Jeep's service manual or seek advice from a mechanic if you are unsure about the location.

Step 4: Disconnect the Old Fuel Filter

Before installing the new fuel filter, you must first remove the old one. Place the catch pan underneath the fuel filter to collect any spilled fuel. Using your wrench or pliers, carefully loosen the connections at both ends of the fuel filter. Once loose, remove the old fuel filter and set it aside.

Step 5: Prepare the New Fuel Filter

Inspect the new fuel filter to ensure it is the correct type and free from any defects. Identify the inlet and outlet ports on the fuel filter, as well as the direction of fuel flow. The inlet port is usually marked with an arrow and is where the fuel enters the filter. The outlet port is where the filtered fuel exits the filter and continues towards the engine.

Step 6: Install the New Fuel Filter

Connect the new fuel filter to the fuel lines, ensuring that the connections are secure and tight. Make sure the fuel lines are properly routed and secured with straps or clamps to prevent any kinks or damage.

Step 7: Start the Engine and Check for Leaks

Once the new fuel filter is installed, start the engine and inspect the fuel filter and fuel line connections for any signs of leaks. If there are no leaks, congratulations! You have successfully installed the fuel filter. If there are leaks, tighten the connections and inspect for any damaged components.

By following these steps, you can ensure a smooth and safe fuel filter installation process for your 304 Jeep, keeping your vehicle running reliably for years to come.

Checking the fuel tank

To check the fuel tank of your Jeep, you will need to drop the tank and remove the old fuel lines. It is recommended to buy steel replacements. Once you have the new lines, get under the Jeep with the new lines, a tubing bender, and some straps/clamps.

Before installing the new lines, check the tank. Get the pick-up and sender out to see if the tank needs cleaning and if the pick-up screen is still there. It is also recommended to check the mounting points and work from there.

If you have a 1979 CJ7, you will need to pull out the two body tub bolts on the right-side centre area and try to slide in the new lines that way. You may need to loosen all the mounts on that side to get the rubber and inner metal sleeve out.

Additionally, if you have a 1976 CJ with a 1975 304 engine, the fuel filter has one line on each end, while the replacement has two lines on one end and one on the other. The extra line is for the fuel recycling/disposal.
