Replacing Fuel Line On John Deere Lt150: A Step-By-Step Guide

If you're having trouble with your John Deere LT150 mower, you might need to replace the fuel line. This can be caused by a clogged fuel line or a faulty fuel pump. Before you begin, make sure to purchase a suitable replacement fuel line for your mower, such as the John Deere Original Equipment Fuel Line #AM122215, which fits the John Deere LT150 model. You will also need to partially drain the tank, as the fuel line outlet is located slightly forward of the middle of the tank. Additionally, removing the deck of the mower first will make the process easier. Once you have the necessary parts and have drained the tank, you can proceed with removing the old fuel line and installing the new one, ensuring a secure connection at both ends.

How to Replace Fuel Line on John Deere LT150

Part number for the fuel line

To replace the fuel line on a John Deere LT150, you will need to purchase a new fuel line with part number #AM122215. This is a genuine John Deere part that fits the John Deere LT150 model, as well as other John Deere riding mower and ZTrak models.

The fuel line can be purchased online from retailers such as Amazon and shipped directly to your location. The price for the fuel line varies by seller but is typically around $13.56.

When replacing the fuel line, it is recommended to also purchase a new fuel pickup tube with part number M132706. This fuel pickup tube is also compatible with the John Deere LT150 model and can be purchased from retailers like Amazon and EvergladesEquipmentGroup.

In addition to the fuel line and fuel pickup tube, you may also need a 1/4 inch ID fuel line for small engines, which can be purchased in a 6-foot length from retailers like Jackson Supplies LLC. This fuel line is compatible with various John Deere models, including the LT150.

By using the correct part numbers and purchasing compatible fuel lines and components, you can ensure a proper fit and efficient fuel delivery system for your John Deere LT150.

Draining the tank

To replace the fuel line on a John Deere LT150, you will need to first drain the tank. Here is a step-by-step guide on how to do this:

Step 1: Prepare the Work Area

Before starting any work on your John Deere LT150, it is important to ensure that you have a safe and clean work area. Park the mower on a flat, level surface, engage the parking brake, and remove the key from the ignition to prevent accidental starting. It is also recommended to wear protective gear, such as gloves and safety goggles, during the draining process.

Step 2: Locate the Fuel Tank

The fuel tank on the John Deere LT150 is located under the mower deck. To access it, you will need to remove the mower deck. Refer to the owner's manual for instructions on how to safely remove the mower deck. Once the deck is removed, you will be able to locate the fuel tank and the fuel line that needs to be replaced.

Step 3: Partially Drain the Fuel Tank

You will need to partially drain the fuel tank to replace the fuel line. The outlet is slightly forward of the middle of the tank. Remove the fuel line from the fuel pump and allow the fuel to drain into a suitable container by gravity. Be very careful when handling gasoline, as it is highly flammable. Ensure you are in a well-ventilated area and avoid any open flames or sparks.

Step 4: Contain the Spill

Place a drip pan or absorbent material under the fuel tank to catch any drips or spills during the draining process. This will help prevent gasoline from coming into contact with the mower components or the ground. It is important to dispose of the drained gasoline properly, following local regulations and guidelines.

Step 5: Continue with Fuel Line Replacement

Once the fuel tank is partially drained, you can continue with the fuel line replacement process. Refer to a repair manual or seek guidance from a qualified technician for detailed instructions on replacing the fuel line. Ensure that you install a compatible fuel line, such as the John Deere Original Equipment Fuel Line #AM122215, which is specifically designed for the John Deere LT150 model.

Fuel line material

The fuel line material for the John Deere LT150 is not explicitly stated, but it is likely to be made from either rubber or Tygon. Rubber is the standard material for fuel lines and will ensure a proper fit. Tygon is a more expensive option that offers improved durability and performance.

When replacing the fuel line, it is important to use a branded product to avoid fake tube materials that are made from recycled chewing gum and will not last long. The fuel line should be compatible with the John Deere LT150 and have the correct dimensions, typically 1/4" ID fuel line.

In addition to the fuel line itself, you will also need a fuel filter, hose clamps, and a fuel pump. These components work together to ensure the proper flow of fuel from the tank to the engine, and replacing them can help resolve issues with the mower not starting or performing poorly.

When purchasing replacement parts, it is recommended to buy genuine John Deere OEM parts to ensure compatibility and quality.

Fuel pump issues

If you're experiencing fuel pump issues with your John Deere LT150, there are a few things you can try to troubleshoot and potentially fix the problem.

Firstly, check whether the fuel pump is functioning correctly. You can do this by turning the engine over with the gas line to the carb off and seeing if it shoots out any gas. If it doesn't, then the issue may lie with the fuel pump itself. If you've recently replaced the pump with a cheaper, non-factory option, it's possible that it's faulty, as low-cost fuel pumps can often be defective straight out of the package.

Another potential issue could be a clogged fuel line. Over time, the fuel line can deteriorate, melt into itself on the inside, and prevent sufficient gas from being pulled into the pump. This can be easily addressed by replacing the fuel line, which is a straightforward and inexpensive fix.

If you suspect that the fuel pump is the problem, you can perform a simple test to confirm. Grab a length of fuel hose, connect it to the inlet side of the pump, and place the other end into a jerry can of fuel. If the pump is functioning correctly, it should be able to draw fuel from the can. If it can't, then it's likely that the pump is faulty and needs to be replaced.

Additionally, it's worth noting that the long fuel line running from the pump to the tank fitting is often a common source of problems. These lines tend to rot after a few years, creating air leaks and making it challenging for the pump to draw fuel. The interior of the line can also degrade and clog the inlet needle valve on the carb, disrupting fuel flow.

If you decide to replace the fuel line, it's recommended to take the mower deck off first to gain better access. You'll also need to partially drain the fuel tank by removing the line from the fuel pump and letting the fuel drain by gravity. The fuel line can then be easily swapped out, as it uses clip-on connections at both ends.

By following these steps, you should be able to identify and resolve any fuel pump issues with your John Deere LT150.

Fuel filter

To replace the fuel filter on a John Deere LT150, you will first need to drain the gasoline tank. The outlet is slightly forward of the middle of the tank, so you can pull the line off at the fuel pump and then back down under the mower. From there, the gasoline will drain via gravity.

It is also recommended to pull the deck off first to make the process easier. You can then split the very end of the tube and peel it back to avoid any strain on the spigot on the tank.

You can find the fuel filter for the John Deere LT150 on Amazon, along with the fuel line and other replacement parts.
