Replacing Fuel Pump In '86 Dodge D150: Step-By-Step Guide

If you're looking to replace the fuel pump in your 1986 Dodge D150, you've come to the right place. This job can be done in a number of simple steps, but first, let's locate the fuel pump. If your D150 has a 318 engine, the fuel pump will be on the front passenger side of the engine, mounted to the side of the timing chain housing. Now, onto the replacement process. Start by disconnecting the fuel lines and removing the mounting bolts. Be sure to use a clamp-type vice grip pliers to prevent fuel from running everywhere. Install the new fuel pump, reconnect the fuel lines, and you're done! This whole process should take no more than 15 minutes.

Disconnect fuel lines and remove mounting bolts

To disconnect the fuel lines and remove the mounting bolts of a 1986 Dodge D150, you'll need to follow these steps:

Firstly, locate the fuel pump on the front passenger side of the engine, mounted to the side of the timing chain housing. It will be below the alternator. Before you begin, ensure you have a clamp-type vice grip pliers to prevent gas from spilling everywhere.

With your tool in hand, simply unhook the fuel line. There should only be two bolts holding it in place, so use your pliers to remove them. Once the bolts are off, carefully remove the fuel pump, being mindful of any gas that may still be in the line.

It is a simple process that can be completed in about 15 minutes, and it is so easy that, as the blogger puts it, "I would bet the ranch that a 5th-grade girl can do it."

Ensure you have the correct replacement part

When replacing the fuel pump on a 1986 Dodge D150, it is important to ensure that you have the correct replacement part. Here are some detailed instructions and considerations to help you obtain the right fuel pump for your vehicle:

First, it is essential to identify the specific model of your Dodge D150. The fuel pump can vary depending on the year and model of your vehicle. In this case, you have a 1986 Dodge D150, so make sure that the replacement part is compatible with that specific model year.

Next, you need to determine the type of fuel pump your vehicle requires. There are two main types of fuel pumps: mechanical fuel pumps and electric fuel pumps. Consult your vehicle's repair manual or seek advice from a trusted mechanic or automotive parts specialist to identify the correct type for your Dodge D150.

When purchasing a replacement fuel pump, it is crucial to buy from a reputable source. Look for authorized dealers or trusted online retailers that specialize in automotive parts. This will help ensure that you are getting a high-quality and genuine product.

Additionally, pay close attention to the specifications and compatibility of the replacement fuel pump. Check the vehicle fitment charts provided by manufacturers or retailers to confirm that the fuel pump is specifically designed for your Dodge D150's make, model, and year.

It is also recommended to compare the original part with the replacement. If possible, visually inspect the old fuel pump and take note of its dimensions, connector type, and any other distinctive features. Compare these with the specifications of the prospective replacement to ensure a match.

Finally, consider the quality and performance standards of the replacement fuel pump. Look for products that meet or exceed the original equipment manufacturer (OEM) specifications. This will ensure that the new fuel pump delivers the same level of performance and reliability as the original part.

By following these guidelines and carefully selecting a replacement fuel pump, you can be confident that you have the correct part for your 1986 Dodge D150, ensuring a smooth and successful installation process.

Check fuel filter and fuel lines for debris

To check the fuel filter and fuel lines for debris, you can follow these steps:

Firstly, locate your fuel filter. In most cars, it will be in line, placed between two sections of the fuel line, usually under the car near the fuel tank. It will resemble a small cylinder. Some cars have an in-line filter located in the engine compartment.

Next, you can check the condition of the paper filter inside, if possible. Some cars have transparent plastic fuel filters, allowing you to see the paper filter. If it appears dark brown or shows signs of sediment, it needs to be replaced. Other filters are sealed steel cylinders that cannot be seen into.

If you notice your car losing power or stalling, especially when pressing the accelerator, you may have a problem with the fuel filter. To further test this, you can perform the following steps with the help of an assistant:

• Loosen the hose clamp on the fuel line that goes into the fuel filter from the tank by turning the clamp screw counter-clockwise with a flat-head screwdriver. Hold the fuel filter tilted slightly upwards, then pull the fuel line off.
• Place the end of the fuel filter over a glass jar. Have your assistant engage the emergency brake, put the car in neutral, and turn the key in the ignition to the first position (do not start the engine). Observe the rate at which the fuel flows into the jar. Then, turn off the ignition and reconnect the fuel line to the filter.
• Loosen the hose clamp on the fuel line that goes from the fuel filter to the engine, as done in the previous step. Hold the hose at a slightly upward angle and pull the filter off.
• Hold the end of the fuel filter over the glass jar and ask your assistant to turn the ignition to the first position again. Observe the rate of fuel flow from the filter. If it is slower than the previous flow rate from the fuel line directly off the tank, your filter is dirty and requires replacement.

If you have replaced the fuel filter due to debris but your car continues to stall, you should replace your fuel lines. The debris in the filter may only represent a small portion of the clogging material in your fuel lines.

Additionally, you should regularly inspect the fuel lines for signs of deterioration or damage, especially after periods of storage. Normal deterioration can occur due to weather conditions and fuel compounds. Replace any worn or damaged fuel lines as soon as possible. Ensure that you do not kink the fuel lines or use tools like pliers when removing them to avoid damage.

Purchase a mechanical or electric fuel pump

When purchasing a mechanical or electric fuel pump for your 1986 Dodge D150, there are a few things to keep in mind. Firstly, it is important to determine the compatibility of the fuel pump with your vehicle. Make sure to check the product specifications and fitment information to ensure that the fuel pump is compatible with the specific make, model, and year of your Dodge D150.

Secondly, consider the type of fuel pump you need. Your 1986 Dodge D150 may have a mechanical fuel pump or an inline electric fuel pump. If it has a mechanical fuel pump, it will be located on the front passenger side of the engine, mounted to the side of the timing chain housing. You can find mechanical fuel pumps for the Dodge D150 on websites like Amazon and eBay, offered by brands such as Carter Fuel Systems and Delphi.

On the other hand, if your vehicle has been modified to include an inline electric fuel pump, you may need to purchase a replacement electric fuel pump. Electric fuel pumps for the Dodge D150 can also be found on Amazon and eBay, offered by brands such as Autobest, Bosch, and Carter. When choosing an electric fuel pump, pay attention to the specifications, such as flow rating, pressure, inlet and outlet types, and compatibility with your vehicle's fuel tank capacity and fuel delivery system.

Additionally, it is recommended to consult with experts or refer to reliable online resources, such as Parts Geek, to determine the best fuel pump option for your Dodge D150. This will ensure that you select a fuel pump that meets or exceeds original equipment (OE) requirements and provides optimal performance and compatibility.

Finally, consider the quality and durability of the fuel pump. Look for products that offer exceptional quality and performance, meeting or exceeding the standards of the original equipment. Some fuel pumps may also come with warranties or guarantees, ensuring their reliability and longevity. By following these guidelines, you can make an informed decision when purchasing a mechanical or electric fuel pump for your 1986 Dodge D150.

Seek expert advice if needed

If you're unsure about any aspect of changing the fuel pump on your 1986 Dodge D150, it's important to seek expert advice. This job can be challenging, and it's crucial to take proper safety precautions when working with flammable liquids.

Start by consulting your vehicle's service manual or online tutorials for guidance. You can also contact experts, such as those at Parts Geek, to determine the best fuel pump for your vehicle. Getting the correct part is essential for restoring your truck to good working condition.

Additionally, consider joining or posting on online forums or communities dedicated to car maintenance and repairs. These platforms often have experienced members who can provide valuable insights and advice.

If you feel that the task is beyond your capabilities or comfort level, don't hesitate to consult a professional mechanic. They have the necessary skills and experience to handle the job safely and effectively.

Remember, attempting to replace the fuel pump without the proper knowledge or precautions can lead to bigger and more expensive problems down the road.
