Testing Your Electra Glide's Fuel Pressure: A Step-By-Step Guide

Testing the fuel pressure of an Electra Glide motorcycle is a straightforward process that can help identify issues with the fuel pump or other components. To perform the test, you will need a fuel pressure gauge that fits a Chevy system, as the test port on the Electra Glide is similar. The port is located on the right side of the bike, between the cylinders, near the bottom of the throttle body. By screwing on the test gauge, turning on the ignition, and observing the pressure, you can determine if the system is functioning correctly. A properly working fuel pump should maintain a pressure of around 58 to 60 psi.

The fuel pressure gauge test port is on the right side, between the cylinders, near the bottom of the throttle body

To test the fuel pressure on an Electra Glide, you'll need to locate the fuel pressure gauge test port. This can be found on the right side of the bike, between the cylinders, near the bottom of the throttle body. It will resemble a tyre valve stem with a cap on it.

Once you've located the test port, you can screw on the test gauge, which you can purchase or loan from most auto parts stores. With the test gauge securely attached, turn on the ignition and listen for the fuel pump to run. Observe whether the system comes up to pressure. Then, start the bike and check if the pressure is maintained. A healthy fuel pump should consistently deliver around 58 to 60 psi.

If the pressure is lower than expected, there may be an issue with the fuel pump or the plumbing in the tank. A common problem area is the plastic cross over tube that connects the fuel pump to the fuel filter, which can develop pinhole leaks.

It is also worth noting that some Electra Glide models have had issues with the fuel flange, which can cause fuel spray or mist inside the tank when the engine is running. If this is the case, you may need to replace the fuel module, which includes the fuel pump, filter, and mounting flange.

The test gauge should be screwed on, the ignition turned on, and the system pressure observed

Testing the fuel pressure on an Electra Glideee involves using a fuel pressure gauge. The test gauge should be screwed on, the ignition turned on, and the system pressure observed.

Firstly, locate the fuel pressure gauge test port. On a Harley Davidson V-Rod, for example, this is on the right side of the bike, between the cylinders, near the bottom of the throttle body. It may look like a tire valve stem with a cap on it. Once you have located the test port, screw the test gauge onto it securely.

Now you can turn on the ignition. You should hear the fuel pump running. Observe the system pressure gauge to see if it comes up to pressure. A Harley Davidson V-Rod, for example, should have a fuel pressure of around 58 to 60 psi.

Next, start the bike and observe whether the system maintains pressure. If the pressure drops, this could indicate a problem with the fuel pump or a leak in the system. For example, a 'pin-hole' leak in the plastic cross over tube that runs between the fuel pump and the fuel filter could cause a drop in pressure.

If you suspect an issue with the fuel pump, further testing can be performed. For example, you can try running the bike at a higher RPM to see if the pressure drops. Additionally, checking for leaks or clogs in the fuel system, including the fuel filter and fuel lines, can help identify any problems.

Start the bike and check if the pressure is maintained

To test the fuel pressure of your Electra Glide, you will need to use a fuel pressure gauge. You can borrow one from a local auto parts store, or purchase your own. The fuel pressure gauge test port is located on the right side of the bike, between the cylinders, near the bottom of the throttle body. It looks like a tire valve stem with a cap on it.

Once you have located the test port, you can begin the test by screwing on the test gauge. Then, turn on the ignition and listen for the fuel pump to run. Check if the system comes up to pressure.

Now, start the bike and check if the pressure is maintained. A well-functioning bike should run somewhere around 58 to 60 psi. If the pressure is maintained within this range, your fuel pump is likely in good condition.

However, if the pressure drops or is inconsistent, it could indicate an issue with the fuel pump or another component in the fuel system. In such cases, further diagnostics and repairs may be necessary.

It is important to exercise caution when working with fuel and a hot engine to prevent any safety hazards. Always refer to the manufacturer's guidelines and seek professional assistance if needed.

The pressure should be around 58 to 60 psi

To test the fuel pressure of an Electra Glide, you'll need to get a fuel pressure gauge. You can borrow or buy one from a parts store, or you might be able to get one from Autozone or Advance Auto Parts, which will refund your money when you return the gauge.

The fuel pressure gauge test port is on the right side of the bike, between the cylinders, near the bottom of the throttle body. It looks like a tire valve stem with a cap on it. Screw on the test gauge, turn on the ignition and listen for the fuel pump to run. A properly functioning fuel pump will cause the system to come up to pressure. Then start the bike and see if it maintains pressure. The pressure should be around 58 to 60 psi.

If the pressure is below 55-60 psi, you may have a faulty fuel pressure regulator. You can test this by turning on the ignition and watching the fuel line overflow. If fuel pours out when the pressure is below 55-60 psi, the regulator is bad and needs to be replaced.

If the pressure is at 58-60 psi, but the bike is still hard to start, you may have a leak in a fuel line inside the tank. This is most likely a hose. To check this, remove the pressure line and securely fit a length of hose to the nipple. Then, use an air compressor or your mouth to blow air into the tank. If there's a leak, you'll feel it or see bubbles.

If the pressure is low, there could be a pinhole leak in the plastic cross over tube

If the fuel pressure is low, there could be a pinhole leak in the plastic crossover tube. This is the tube that runs between the fuel pump and the fuel filter. To fix this, you'll need to locate the leak, turn off the fuel supply, dry the area, and then apply a patch. Here's a step-by-step guide:

Step 1: Locate the Leak

Pinhole leaks can be tricky to spot, so inspect the plastic crossover tube carefully for any signs of moisture or dripping fuel.

Step 2: Turn Off the Fuel Supply

Before attempting any repairs, it's crucial to turn off the fuel supply to prevent further leakage and potential safety hazards.

Step 3: Dry the Area

Use a clean cloth to absorb any fuel around the leak. This will give you a better view of the damaged area and ensure a stronger bond when applying the patch.

Step 4: Prepare the Area

Using sandpaper, gently sand the area around the leak to create a smoother surface for the patch to adhere to. Remove any rough edges or debris.

Step 5: Apply a Patch

Apply a thin layer of primer to the area, then use PVC cement to attach a rubber patch over the leak. Make sure the patch is centred and covers the entire damaged area. Press down firmly and allow the cement to dry completely before turning the fuel supply back on.

Step 6: Test the Repair

Once the repair is dry, turn on the fuel supply and check for any signs of leaking. If the repair was successful, you should now have normal fuel pressure.

It's important to address pinhole leaks as soon as possible to prevent further issues. Additionally, consider replacing the tubing if it's showing signs of wear or if your bike has high mileage. Taking proactive measures can help prevent unexpected breakdowns and ensure a smoother riding experience.
