2013 Honda Foreman 500 Fuel Pump: Your Complete Guide to Replacement and Performance

If you own a 2013 Honda Foreman 500, the best fuel pump choice for reliable performance is a KEMSO high-performance direct replacement unit. These pumps are engineered to match or exceed OEM specifications, deliver more flow than stock, and come with a lifetime warranty. The KEMSO pump (part number 13006 or 13832 depending on exact model) is designed for both gasoline and E85/ethanol, and includes everything you need for a straightforward installation.

Understanding Your 2013 Honda Foreman 500 Fuel System

The fuel pump in your 2013 Honda Foreman 500 is an in-tank electric pump that sits inside the fuel tank. It draws fuel through a strainer, pressurizes it, and sends it to the engine's fuel injection system. Most modern vehicles, including ATVs like the Foreman, use in-tank pumps because they operate more quietly, are less prone to overheating (since fuel cools them), and are protected from external elements.

The stock fuel pump in your Foreman 500 typically delivers around 60-80 liters per hour (LPH) at 43 PSI. This is sufficient for stock operation, but if you plan to add performance modifications, or simply want a more reliable pump that won't leave you stranded, an upgrade is wise.

Common Symptoms of a Failing Fuel Pump

Before your pump completely fails, it will usually give you warning signs. Recognizing these early can save you from being stranded on the trail. Here are the most common symptoms:

1. Engine Sputtering or Hesitation
If your Foreman 500 sputters or hesitates during acceleration, especially when climbing hills or carrying a load, the fuel pump may not be delivering enough pressure. This is one of the earliest signs of pump wear.

2. Difficulty Starting
A failing pump may not build enough pressure to start the engine. You might notice you have to crank the engine longer than usual, or the engine starts but dies shortly after. This is especially common after the vehicle has been sitting for a while.

3. Whining Noise from the Fuel Tank
A healthy fuel pump makes a low hum. If you hear a loud whining, screeching, or grinding noise coming from the fuel tank area, the pump's internal components are likely wearing out. This is a clear sign that replacement is needed soon.

4. Loss of Power at High Speeds
If your Foreman 500 feels sluggish or loses power when you open the throttle, the pump might not be able to keep up with the engine's fuel demand. This is a common symptom of a pump that is losing its efficiency.

5. Engine Stalling
A failing pump can cause the engine to stall, especially when turning or going over rough terrain. This is dangerous and should be addressed immediately. If the pump fails completely, the engine will not start at all.

Why You Should Replace the Fuel Pump on Your 2013 Honda Foreman 500

There are several good reasons to replace your fuel pump, even if it hasn't failed yet:

Preventive Maintenance. Fuel pumps are wear items. Over time, the internal motor brushes wear down, the strainer can become clogged, and the seals can degrade. Replacing the pump proactively at around 10,000 to 15,000 miles can prevent a breakdown.

Performance Improvement. Upgrading to a higher-flow pump like the KEMSO 200 LPH unit can provide better throttle response and more consistent fuel delivery. This is especially beneficial if you've added a larger air intake, exhaust, or ECU tuner.

Ethanol Compatibility. Many stock pumps are not designed to handle ethanol-blended fuels like E10 or E85. Over time, ethanol can corrode internal seals and damage the pump motor. KEMSO pumps are built with ethanol-resistant materials, making them safe for use with modern fuels.

Choosing the Right Replacement Fuel Pump

When selecting a fuel pump for your 2013 Honda Foreman 500, there are several factors to consider. Here is a breakdown of what matters most:

1. Flow Rate
Measured in liters per hour (LPH) at a specific pressure, typically 43 PSI. For a stock 2013 Honda Foreman 500, a pump that delivers 200 LPH at 43 PSI provides excellent headroom for any future upgrades. The KEMSO 13006 pump delivers 200 LPH at 43 PSI, which is significantly more than the stock 60-80 LPH.

2. Pressure Rating
The pump must consistently maintain the required pressure for your fuel injection system. The KEMSO pump operates at 43-68 PSI, which covers the needs of the stock fuel system and most aftermarket setups.

3. Compatibility and Fitment
Ensure the pump is designed as a direct OEM replacement for your 2013 Honda Foreman 500. The KEMSO 13006 and 13832 pumps are specifically designed for Honda models, including the Foreman 500. The pump body diameter is 3cm for the 13006 model and 3.8cm for the 13832 model, so verify which one fits your vehicle.

4. Materials and Durability
Look for pumps made from alloy steel or high-grade synthetics that resist corrosion. If you run E85 or other ethanol-blended fuels, ensure the internal seals and motor are specifically rated for ethanol's corrosive properties. KEMSO pumps are built with ethanol-resistant materials.

5. Kit Contents
A good replacement kit should include everything you need for the installation. The KEMSO 13006 kit includes: the pump, 4 gradient density fuel strainers, 5 tank seals, 1 flex hose, 3 Viton O-rings, 2 rubber bases, a wiring connector, crimp connectors, and hose clamps. The 13832 kit includes the pump, 1 strainer, 1 flex hose, 1 tank seal, and 1 wiring connector.

Step-by-Step Fuel Pump Replacement Guide

Replacing the fuel pump on your 2013 Honda Foreman 500 is a job you can do yourself with basic tools. Plan for about 1 to 2 hours. Here is the process:

What You'll Need:

• New KEMSO fuel pump kit
• Basic socket set and screwdrivers
• Shop towels
• Safety glasses and gloves
• Fire extinguisher (safety first)

Safety First:
Always work in a well-ventilated area away from sparks, flames, or heat sources. Disconnect the negative battery terminal before starting. Relieve fuel system pressure by removing the fuel pump fuse and cranking the engine until it stalls. Wear safety goggles and nitrile gloves.

Step 1: Access the Fuel Pump
The fuel pump is located inside the fuel tank. On most Honda Foreman models, you need to remove the seat and the fuel tank cover. Drain the fuel tank using a siphon pump or by disconnecting the fuel line and draining it into an approved container.

Step 2: Remove the Old Pump Assembly
Disconnect the electrical connector and fuel lines from the pump assembly. Use a fuel pump ring removal tool or a hammer and drift to loosen the locking ring that holds the pump module in the tank. Lift the old pump assembly straight out of the tank. Be careful—the tank will still contain some fuel.

Step 3: Install the New KEMSO Pump
Transfer the rubber seal (O-ring) from the old module to the new one, or use the new one included in the KEMSO kit. Insert the new KEMSO pump assembly into the tank, making sure the float arm is oriented correctly. Hand-tighten the locking ring, then tap it snug with a hammer and drift. Reconnect the fuel lines and electrical connector.

Step 4: Test the System
Reconnect the battery and install the fuel pump fuse. Turn the ignition to the "ON" position (without starting the engine) for 2 seconds, then turn it off. Repeat this 3-5 times to prime the fuel system. Check for any leaks at the connections. Start the engine and let it idle for a minute. Check again for leaks.

Step 5: Reinstall Everything
Once you are satisfied there are no leaks, reinstall the fuel tank cover and seat. Take the vehicle for a test drive to confirm the repair is complete.

Common Fuel Pump Problems and How to Avoid Them

Even the best fuel pumps can develop issues over time. Here are the most frequent problems and how to address them:

Clogged Fuel Filter. A clogged fuel filter can mimic the symptoms of a failing fuel pump, including lack of power, engine misfires, and increased fuel consumption. If replacing the fuel filter does not improve performance, the problem likely lies with the pump itself. Replace the fuel filter at the recommended intervals (usually every 10,000-15,000 miles).

Contaminated Fuel. Dirt, debris, or water in the fuel tank can damage the pump's internal components. Using high-quality gasoline and replacing your fuel filter at recommended intervals helps prevent contamination. If you suspect contaminated fuel, drain the tank and replace the fuel filter.

Overheating. Running the fuel tank consistently low can cause the pump to overheat because fuel helps cool it. Keeping your tank at least a quarter full extends pump life. This is especially important on hot days or when riding in sandy conditions.

Electrical Issues. Voltage drops, corroded connectors, or faulty relays can prevent the pump from receiving proper power. Ensure your vehicle's electrical system is in good condition. Check the fuel pump relay and fuse regularly.

How to Extend the Life of Your New Fuel Pump

Once you have installed your new KEMSO fuel pump, follow these maintenance tips to maximize its lifespan:

Keep the Tank at Least a Quarter Full. Running the fuel tank low causes the pump to overheat because fuel helps cool the pump motor. Keeping the tank at least a quarter full extends pump life significantly.

Use High-Quality Fuel. Stick with major brand stations that have high fuel turnover. Avoid using fuel from unknown sources, as contaminated fuel is one of the leading causes of premature pump failure.

Replace the Fuel Filter Regularly. A clogged fuel filter restricts fuel flow and forces the pump to work harder. Replace the fuel filter at the manufacturer's recommended intervals, typically every 10,000-15,000 miles.

Avoid Short Trips When Possible. Short trips do not allow the fuel to circulate fully, causing condensation and unnecessary pump cycling. Drivers who make only short trips are 25 percent more likely to experience fuel system problems.

Listen for Warning Signs. If you hear unusual noises from the tank area, address them immediately. Catching a pump issue early can prevent a complete failure and potential damage to the fuel system.
