Gas tank bungs for motorcycles
Gas tank bungs are an essential component of a motorcycle's fuel system, providing a secure and tight seal for the gas tank. They are available in various materials, including aluminum and steel, and play a crucial role in ensuring the safe and efficient functioning of the motorcycle's fuel system.
When it comes to motorcycles, the size and type of gas tank bung can vary depending on the make and model of the bike. Some motorcycles, like the Harley Sportster, may require specific parts for a custom gas tank setup. In general, gas tank bungs for motorcycles are designed to be snug fits, with threaded steel bungs being a popular option. These threaded bungs allow for secure mounting of the gas tank and provide a tight seal to prevent fuel leaks.
One important consideration when working with gas tank bungs is the need to strip paint from the frame before welding or mounting the bungs. This is a crucial step, as mentioned in a guide by Lowbrow Customs, where they emphasize stripping paint from the area where the tank tabs will sit. Additionally, they highlight the importance of removing any braze present, as it can interfere with the welding process and cause issues like porosity.
The process of mounting a gas tank using threaded steel bungs involves marking the center point of the backbone and utilizing fabrication parts such as bungs, tabs, and brackets. It is important to ensure that the washers are centered and aligned correctly to achieve a visually pleasing result and protect the paint. Leather washers, for instance, can help prevent damage to the clear coat.
When it comes to the size of the bung in a fuel storage tank, it can vary depending on the specific application and fuel tank type. In the context of motorcycles, a common size mentioned is 1/4" rubber hose, indicating that the bung size would accommodate this specific hose dimension. It is always important to use the appropriate size bung for your motorcycle's fuel tank to ensure a proper seal and prevent leaks.

Marine tank fittings
When it comes to marine tank fittings, there are a variety of options available to suit your specific needs. Marine fuel tank fittings are an essential component of any boat or ship, ensuring the safe and efficient transfer of fuel.
One important consideration is the size of the fittings, which should match the dimensions of your fuel tank and fuel line. Universal marine tank quick connector fittings, for instance, typically feature a 3/8" female fitting for the fuel line hose and a 1/4" male NPT fitting for connection to the fuel tank.
The type of fitting is also a key factor. You can choose from a range of options, including fuel tank bulkhead fittings, marine fuel lines, marine fuel tank vents, and marine fuel fills. It's important to select a fitting that is compatible with your fuel system and designed for marine use to ensure safety and durability in the harsh marine environment.
Materials used in marine tank fittings are equally important. Stainless steel and nylon are common choices for their durability and corrosion resistance. Stainless steel, in particular, offers excellent resistance to saltwater and marine conditions, making it ideal for marine applications.
Finally, when purchasing marine tank fittings, it's advisable to source them from reputable suppliers or manufacturers. This ensures that the fittings meet industry standards and are of high quality. Retailers like Amazon and Walmart offer a wide range of marine fuel tank fittings, connectors, and accessories, providing a convenient option for boat owners and marine businesses alike.

Bungs for fuel feed tubes
Bungs are an essential component of fuel storage and feed systems, ensuring secure connections and access to fuel supplies. When it comes to fuel feed tubes, bungs play a critical role in facilitating the transfer of fuel from the storage tank to the engine. Here's what you need to know about bungs for fuel feed tubes:
Types of Bungs for Fuel Feed Tubes
There are various types of bungs designed specifically for fuel feed tubes. These include:
- Fuel Tank Bungs: These bungs are designed to be mounted on the surface of the fuel tank and attached with metal screws. They simplify the installation of fuel feed lines, ensuring a secure connection for the fuel feed tube. Fuel tank bungs often require sealing with fuel-resistant epoxy to prevent leaks.
- Motorcycle Gas Tank Bungs: Customizable gas tank bungs are available for motorcycles, catering to bike builders looking to personalize their fuel systems. These bungs are typically made of aluminum or steel and can be tailored to specific requirements.
- Powersports Fuel Tank Feed Bungs: These bungs are designed for powersports enthusiasts, allowing them to tap into their fuel supply to feed their nitrous systems. They require a specific hole size for installation and feature a mesh screen to keep debris out of the fuel supply.
Sizing and Compatibility
The size of the bung is crucial to ensure a proper fit and secure connection with the fuel feed tube. Bungs for fuel feed tubes typically have specific dimensions, such as the Powersports Fuel Tank Feed Bung, which requires a 9/16" hole for installation and has a 5/16" hose barb size. It's important to refer to the manufacturer's specifications and recommendations to select the correct bung size for your fuel feed tube application.
Sealing and Leak Prevention
To prevent fuel leaks, it is essential to properly seal the bung and the fuel tank mating surfaces. Fuel-resistant epoxy products, such as Pro Seal, are commonly used to create a secure and leak-free connection. Additionally, some bungs, like the Powersports Fuel Tank Feed Bung, come with seals included to ensure leak-free performance.
