How To Fuel Pressure Test Your Can-Am Outlander

The Can-Am Outlander is an ATV (all-terrain vehicle) that has been in production since at least 2008. Some Can-Am Outlander owners have reported issues with their vehicles, such as low/no power and random misses and sputters. In this case, the problem could be related to fuel pressure or a bad fuel pump. To test the fuel pressure, owners will need a tee and a gauge that can measure a minimum of 55 PSI, as the target pressure is 51 PSI. It is also possible to purchase a fuel pressure tester kit, but some owners have chosen to make their own setup.

Fuel pressure tester kit

A Fuel Pressure Tester Kit is a tool that allows you to safely test car and truck fuel pressure systems. It is designed to work with fuel injected vehicles that have a Schrader valve test port on the fuel rail. This includes Ford high-pressure central fuel injection and GM, Ford, and Chrysler multi-port fuel injection systems.

The kit includes a fuel pressure tester with a large, easy-to-read 0-100 psi scale, solid brass fittings, and a pressure relief valve for safe and clean testing. It can be used to test the fuel pump check valve, fuel pressure regulator, fuel line integrity, and for leaking injectors.

There are a variety of fuel pressure tester kits available on the market, with prices ranging from $33 to $172. Some examples include:

• BlueDriver Fuel Pressure Tester Kit ($33.95)
• Performance Tool W80595 Fuel Injection Pressure Tester ($33.25)
• Basic Fuel Injection Pressure Tester ($69.30)
• Tool Aid TA56250 Multi-Port Fuel Injection Pressure Tester System ($172.89)

When testing the fuel pressure on a Can-Am Outlander, it is recommended to have a "tee" and a gauge that can handle a minimum of 55 psi, as the target pressure is 51 psi.

Fuel pump replacement

Step 1: Park the vehicle and test the fuel pump

Park your vehicle on a firm, level surface and engage the parking brake. Locate the fuel pump, which is usually in the fuel tank. Open the fuel cap and turn the key to the "ON" position. Listen at the filler opening—if the fuel pump is working properly, you should hear a brief hum lasting two to three seconds. If you don't hear this sound, the pump may need to be replaced.

Step 2: Check the fuel pump fuse and relay

Locate and verify the fuel pump fuse and relay. If the fuse is blown, replace it with one of the same amperage. If the fuse and relay are functional, check for power and ground at the fuel pump. If there is power and ground, the pump is faulty and should be replaced.

Step 3: Prepare for fuel pump replacement

Before beginning the replacement process, relieve the fuel system pressure. Disconnect the negative battery cable. Drain as much fuel as possible from the fuel tank. You may need to remove the back seat or use a jack to access and support the fuel tank.

Step 4: Remove the old fuel pump

Disconnect the filler tube hose and electrical connection to the pump. Remove any retaining straps or bolts holding the tank to the frame. Disconnect the fuel lines and remove the old fuel pump from the tank.

Step 5: Install the new fuel pump

Compare the new fuel pump to the original to ensure you have the correct part. Connect the fuel lines to the new pump. Lift the fuel tank into place and secure it with the retaining strap. Reconnect the filler tube hose and electrical connector.

Step 6: Reattach the battery cable and test the vehicle

Reconnect the negative battery cable. Fill the fuel tank and conduct a road test to confirm that the new fuel pump is functioning properly.

Additional Tips:

• Work in a well-ventilated area to minimize the risk of fire and inhalation of fumes.
• Always wear safety gear, such as gloves and eye protection, when handling fuel.
• Drain the fuel tank to reduce the risk of spills and make it easier to handle.
• Clean around the fuel pump to prevent debris from falling into the tank.
• Consider replacing related components, such as the fuel filter and fuel pump strainer.

Fuel pressure gauge

To test the fuel pressure on a Can-Am Outlander, you will need a fuel pressure gauge that can measure a minimum of 55 psi, as the target pressure is 51 psi.

You can either purchase a fuel pressure testing kit or make your own setup. If you want to make your own, you will need to purchase an injector fitting, a manifold block, a suitable gauge, hose, and hose barbs.

To test the fuel pressure, first, pull the fuel pump fuse and start the engine until it won't run anymore. Then, disconnect either injector hose and connect the gauge. Replace the fuse and start the bike. You should be looking for a constant 51 psi while the bike is running.

It's important to note that pulling the fuse will create an error code in the ECM, but it won't affect the running of the bike. You can get your dealer to clear the history the next time you have it hooked up.

Additionally, make sure your fuel system and injectors are clean before testing.

Fuel pump fuse

If you're experiencing issues with your Can-Am Outlander, it may be time to perform a fuel pressure test to diagnose the problem. One of the key components involved in this process is the fuel pump fuse, which is responsible for protecting the fuel pump from electrical surges. Here's a detailed guide to help you understand and address any issues related to the fuel pump fuse:

Locating the Fuse Box:

Start by locating the fuse box, which is typically hidden from view. Refer to your Can-Am Outlander's driver's manual to identify the location of the fuse box specific to your model. It may be under the hood, under the kick panel, or in the trunk area. The driver's manual will also help you identify the fuel pump fuse number, rating, and colour, making it easier to locate the correct fuse in the box.

Checking the Fuel Pump Fuse:

Once you've located the fuse box, follow these steps:

• Remove the fuse: Use the fuse puller tool attached to the fuse box cover or a small pointy nose plier to gently pull the fuel pump fuse upwards and remove it.
• Inspect the fuse: Hold the fuse up to the light and look through the opaque body. You'll see a metallic strip inside. If this strip is broken, your fuse has blown and needs to be replaced.
• Replace with correct rating: Fuel pumps typically use 15 (blue), 20 (yellow), or 25 (clear) amp fuses. Using a fuse with the wrong rating can lead to further issues, so be sure to match the rating specified in your driver's manual.

Troubleshooting Fuel Pump Issues:

If you've checked or replaced the fuel pump fuse and are still experiencing problems, there are a few other potential causes to explore:

• Bad connector at the pump
• Bad wiring between the fuse box and pump
• Faulty crank position sensor (CKP)
• Inertia switch activation or fault

Testing Fuel Pump Operation:

To determine if your fuel pump is functioning properly, try the following:

• Listen for the hum: Most electric fuel pumps emit a faint hum when they turn on for about two seconds to pressurize the fuel rail (priming). If you don't hear this hum, it could indicate an issue with the pump.
• Tap on the gas tank: Bang on the bottom of the gas tank with your hand while a helper turns the key on. If this action gets the pump to fire up, it suggests that the wiring is intact, but the fuel pump may be failing.
• Power the pump directly: Using a power probe or a fused jumper wire, add power to pin socket 87 of the fuel pump relay socket. If the pump runs, the load side of the circuit is functional, and you can focus your attention on the control side.

Checking the Fuel Pump Circuit:

The fuel pump circuit consists of a control side and a load side. To test each side:

• Control side:
• Check for ground at pin 85 socket. If ground is present for two seconds, your relay is controlled by the PCM on the ground side.
• Test for power at pin 86 socket. If power is present for two seconds, your relay is controlled by the PCM on the power side.
• Load side:
• Check for power at pin 30 socket. If there's no power, check the circuit for an open.
• Power pin 87 socket and see if the pump runs. If it doesn't, check for power at the pump using a test light or voltmeter to identify a potential broken wire.

If all tests indicate that the fuel pump and circuit are functioning properly, you may need to consult a mechanic for further diagnosis and repair.

Fuel filter

The fuel filter in the Can-Am Outlander is located inside the fuel tank. To access it, you will need to remove the fuel tank from the vehicle. Once you have removed the fuel tank, you can locate the fuel filter, which is usually attached to the fuel pump assembly.

The fuel filter plays a crucial role in the vehicle's fuel system. It helps to remove contaminants and debris from the fuel before it enters the engine. Over time, the fuel filter can become clogged, which can lead to reduced fuel flow and engine performance issues. Therefore, it is essential to regularly inspect and replace the fuel filter as part of your vehicle's maintenance routine.

When inspecting the fuel filter, look for any signs of clogging or damage. If the filter appears dirty or clogged, it is recommended to replace it with a new one. You can purchase a replacement fuel filter from your local automotive parts store or online.

Additionally, it is important to use high-quality fuel and avoid contaminated fuel sources to prevent clogging and ensure the longevity of your fuel pump and fuel filter.

By following these maintenance tips and regularly inspecting your fuel filter, you can help ensure the optimal performance of your Can-Am Outlander and avoid fuel-related issues.
