Customer Questions & Answers

  • Question: What is a Fuel Check Valve and how does it work?

    Answer: A Fuel Check Valve prevents backflow in your fuel system, ensuring that fuel flows in only one direction. It is a crucial component in maintaining system pressure and preventing contamination. When fuel is pumped, it opens to allow flow; when the pump stops, it closes to prevent backflow. This is particularly important in automotive and industrial applications where efficiency and safety are priorities.
  • Question: What are the dimensions and specifications of the Fuel Vent Roll Over Valve?

    Answer: The Fuel Vent Roll Over Valve features a 12 NPTF thread for male mounting, designed to fit standard fuel tanks and systems. With a 5/16 inch outlet, it allows for effective air venting while preventing fuel spillage during a rollover incident. This valve is commonly used in racing applications, boats, and equipment where fuel stability is essential.
  • Question: How can I determine if a Fuel Safety Valve is necessary for my vehicle?

    Answer: A Fuel Safety Valve is important if your vehicle or equipment frequently operates under fluctuating temperatures or in environments prone to spills. If you notice potential leaks or if your fuel system lacks adequate backflow protection, consider upgrading to a Fuel Safety Valve to enhance operational safety and efficiency.
  • Question: Can the Fuel Gas Tank Rollover Safety Vent Valve Assembly be installed by a DIYer?

    Answer: Yes, if you have basic mechanical skills and the right tools, the Fuel Gas Tank Rollover Safety Vent Valve Assembly can be installed as a DIY project. Make sure to follow the installation instructions carefully and ensure that all connections are secure to maintain fuel system integrity, particularly in automotive or marine applications.
  • Question: What applications can benefit from using this Fuel Vent Roll Over Valve?

    Answer: This Fuel Vent Roll Over Valve is ideal for a variety of applications, including automotive fuel systems, marine fuel tanks, and even industrial equipment. It's particularly beneficial in environments where fuel stability is essential for safety and performance, such as in racing cars, boats, and heavy machinery.
  • Question: What materials is the Fuel Check Valve made from?

    Answer: The Fuel Check Valve is typically constructed from durable materials such as brass or high-grade plastic, designed to withstand corrosive fuel types and high pressure. This robustness ensures that the valve functions effectively without degradation over time, making it suitable for long-term use in various fuel systems.
  • Question: Is the Fuel Vent Roll Over Valve compatible with ethanol-blended fuels?

    Answer: Yes, the Fuel Vent Roll Over Valve is designed to be compatible with most fuel types, including ethanol-blended fuels. However, ensure that the materials used in your specific valve assembly are rated for such fuels to maintain the integrity and safety of your fuel system.
  • Question: What is the role of venting in fuel systems?

    Answer: Venting is crucial in fuel systems as it allows air to replace the fuel being drawn into the engine, preventing a vacuum that could impede fuel flow. Additionally, proper venting prevents pressure buildup, which can lead to leaks or ruptures in the fuel system, enhancing overall safety and efficiency.
  • Question: Can I use a Fuel Check Valve with a fuel filter?

    Answer: Absolutely, a Fuel Check Valve can be effectively used in conjunction with a fuel filter to enhance your fuel system's efficiency. The check valve will ensure consistent fuel flow and pressure while the filter removes impurities, providing cleaner fuel delivery to your engine for optimal performance.

MADHORNETS Selector Valves 90-00945 Editorial Review

The MAD HORNETS Fuel Check Valve Fuel Vent Roll Over Valve has garnered a mix of experiences from customers, primarily centered around the compatibility and fitting of the valve's threads. Many users expressed frustration with the valve's thread dimensions, stating that the 1/2” NPTF threads do not align with standard fittings. This issue has led to significant difficulties in finding appropriate attachments, causing several customers to abandon the product altogether after multiple unsuccessful attempts to connect it to various fuel cell fittings. On the positive side, one reviewer highlighted the valve's performance when it works properly, indicating that it does function effectively once connected. However, the struggle to find compatible fittings overshadows this benefit, as multiple customers report that the threads appear to be straight instead of tapered, which makes them incompatible with typical national pipe thread standards. This disconnect between the product description and actual user experience has led to a general Consensus that the thread design hinders the overall utility of the valve. In summary, while the MAD HORNETS Fuel Check Valve may operate as intended for some, its effectiveness is heavily compromised by significant issues regarding fitting compatibility. Prospective buyers should be cautious and Consider these compatibility issues before purchase. **
