Polaris Sportsman 570 is an ATV (all-terrain vehicle) that has been in production since at least 2014. Some users have reported issues with the fuel vent line, including fuel leaks, strong fumes, and dripping. There are several potential solutions to these problems, including re-routing the vent hose, adding a metal shield between the head and gas tank, and replacing the fuel line with a higher-rated one. Some owners have also experienced issues with the fuel pump, which may be related to excess heat from the header pipe. This can be mitigated by installing an aluminium heat shield, which is available on newer models.

What You'll Learn
Re-route the vent line to prevent fuel from condensing
Re-routing the vent line is a potential solution to the issue of fuel condensing in a Polaris 570 Sportsman. This issue is caused by a build-up of pressure in the fuel tank, which can force gas out and cause a boiling appearance, as well as strong fumes and even drips from the hose.
One solution is to re-route the vent line to release the pressure. This can be done by first identifying the cause of the pressure build-up. In some cases, it may be due to a blocked or pinched vent hose, which can create a vacuum as the volume of gas decreases. This vacuum can starve the fuel pump of fuel and attract moisture and dust, which can mix with the fuel.
To remedy this, ensure the vent hose is clear and free of any obstructions. The vent line can then be re-routed to ensure proper ventilation and prevent future blockages. One method is to bring the vent line down from the top, along the side, and then down through the bottom of the rear floor. However, this may cause issues when filling up the tank, as the vent line may need to be above the fuel fill neck to function properly.
Another method is to follow the F.A.T.S. (Fuel Air Transmission System) way of routing the line. This involves using a longer hose and routing it above the gas cap, similar to an overflow vent. This ensures that the vent line is higher than the fuel level, allowing for proper ventilation and preventing fuel from spitting out during filling.
It is important to note that these are general guidelines, and the specific steps may vary depending on the make and model of your Polaris 570 Sportsman. Always refer to the owner's manual or seek professional assistance if you are unsure about any of the procedures.

Insulate the fuel tank to reduce fuel temperature
Insulating your fuel tank can help to maintain a set temperature range, ensuring the stability of the fuel inside and improving the production process. It can also prevent the fuel from freezing or deteriorating due to heat caused by solar radiation. For your Polaris Sportsman 570, you can consider the following methods to insulate your fuel tank and reduce fuel temperature:
Firstly, understand the factors influencing your choice of insulation material. The best thermal insulation material will depend on the location of your fuel tank, the type of fuel it holds, and the material of the tank itself. Most fuel tanks are made of steel or stainless steel, which are highly conductive and susceptible to heat transfer and corrosion.
Next, consider the different types of insulation materials available. Common and inexpensive materials include lightweight composites and foams, such as fiberglass, mineral wool, silica, cellulose, and ceramics. However, lightweight materials may trap moisture between the insulation and the tank surface, leading to corrosion. More effective options include spray-on foam insulation, panel systems, or custom-designed solutions.
Panel systems, for example, use vertical or horizontal panels that are stacked in rings around the tank. Vertical panels are generally more reliable, easier to install, and more resistant to moisture intrusion than horizontal panels.
Additionally, consider flexible mattresses (jackets) that can provide insulation for the tank and easy access to components. This method is often used for large-diameter storage tanks and their pumping stations and pipelines.
Remember, the right insulation system will depend on your specific needs and requirements. By choosing the proper insulation, you can increase the lifespan of your fuel tank and protect the fuel it holds.

Install an aluminium heat shield to prevent fuel smell and bubbling
If you own a Polaris Sportsman 570, you may have experienced issues with fuel smell and bubbling. While there are a few potential causes and fixes for this problem, one solution that has proven effective is the installation of an aluminium heat shield.
The fuel tank in the Polaris Sportsman 570 is known to build up pressure, which can force gas out of the overflow and cause a strong fuel smell. This issue is exacerbated when the machine is worked hard or ridden in hot weather. One way to alleviate this problem is by installing a heat shield between the head and the gas tank.
To install an aluminium heat shield, you will need to purchase a compatible part for your Polaris Sportsman 570. The part number for the heat shield is #5263226, and it fits the 2014, 2015, and 2016 models of the Polaris Sportsman 570. You can also find used heat shields for sale online, specifically for the 2017 model.
Once you have the correct part, the installation process involves removing the front plastic, side plastic, fuel line, vent tube, and pump connector. You will also need to remove the two bolts that hold the fuel tank in place. The heat shield mounts at the top using these two bolts, and the bottom of the shield can be secured with a cable tie or an additional bolt.
After installing the aluminium heat shield, you should notice a significant reduction in fuel smell and bubbling. This simple modification can greatly improve your riding experience and help prevent fuel-related issues with your Polaris Sportsman 570.

Check for clogs in the fuel line
If your Polaris Sportsman 570 ATV is not running as it should, a clogged fuel line could be the culprit. There are several signs that suggest your fuel line is blocked. For instance, if your engine is not getting enough fuel, you may experience difficulty starting the vehicle, sputtering, stalling, or a lack of power. You may also notice that your ATV is having trouble accelerating, or that it suddenly shuts off while riding. In addition, you may observe smoke inside the vehicle, which is a dangerous sign as it indicates the presence of carbon monoxide due to gas flowing back into the tank and leaking into the engine.
To check for clogs in the fuel line, you can start by inspecting the fuel filter, as it tends to clog before the fuel line itself. Replace the fuel filter if necessary and test the fuel pressure with a fuel pressure tester. If the fuel pressure drops significantly, it indicates a blockage or a faulty fuel pump. Another way to check for clogs is to try to blow into the vent hose; if you are unable to do so, it suggests that the one-way valve is not allowing air into the tank, which can cause pressure to build up.
It is important to address any suspected clogs in the fuel line promptly to prevent further complications. If you are unsure or uncomfortable performing these checks yourself, it is recommended to consult a professional mechanic or a specialised service centre, such as LinesToGo or McCurley's Shell, who can diagnose and resolve the issue. They may suggest cleaning or replacing the fuel line, as well as other maintenance procedures like regularly changing the fuel filter and purchasing quality gasoline to prevent future clogs.
By being vigilant about potential clogs in the fuel line and taking the necessary steps to address them, you can help ensure the optimal performance and longevity of your Polaris Sportsman 570 ATV. Remember, fuel system maintenance is just as crucial as regular oil changes to keep your vehicle running smoothly and safely.
