Replacing The Fuel Tank Of Your Exceed Rc Car

If you're looking to replace the fuel tank on your Exceed RC car, there are a few things you'll need to consider. Firstly, make sure you have the correct starter kit, as the Exceed RC Infinitive Nitro Gas-powered truck requires a starter kit that is sold separately. It's also important to note that the fuel tank has a perfect calibre, making it impossible to overflow, so you won't have to worry about spills when refuelling.

When it comes to actually replacing the fuel tank, you might want to consider adding an extra tank instead of replacing the existing one. This can be done by using a T connector to connect the two fuel and pressure lines. Alternatively, you can set up the tanks in a sequential configuration, which will ensure that both tanks drain completely.

Using a T connector to connect two fuel and pressure lines

When connecting two fuel and pressure lines using a T-connector, it is important to ensure that the connection can withstand the pressure of the fuel line and that there is a secure seal to prevent leaks. Here is a step-by-step guide:

• Prepare the Fuel Lines: Before beginning the connection, ensure that the fuel lines are cut to the appropriate length and that any old fittings or debris are removed. It may be necessary to use a line wrench or a flare nut wrench to remove stubborn fittings. Also, ensure the correct thread type for your fuel system. The most common type is NPT, which is a tapered thread, but other types like UNF (straight thread) may be used.
• Choose the Correct T-Connector: Select a T-connector that matches the size and type of your fuel lines. The T-connector should be made of a suitable material, such as brass or stainless steel, and be rated for high-pressure applications.
• Prepare the T-Connector: If necessary, flare the ends of the fuel lines that will be connected to the T-connector. This can be done using a flaring tool or a swedging tool. Ensure that the flare matches the type of connector being used (e.g., double flare for a double flare union).
• Assemble the Connection: Insert the fuel lines into the T-connector, ensuring that they are securely seated. If the T-connector has threads, use a suitable thread sealant that is resistant to fuel and solvents. Do not use Teflon tape, as it can break free and cause clogging issues.
• Secure the Connection: Use hose clamps to secure the fuel lines to the T-connector. Marine-grade stainless steel clamps are recommended, and it is advisable to use two clamps at each connection point for added security. Ensure that the clamps are tightened evenly to avoid leaks.
• Pressure Test and Inspect: Once the connection is made, have the fuel system pressure-tested by a professional to ensure that there are no leaks or siphoning hazards. This step is crucial for safety, especially if the work involves installing fuel tanks or repowering a vessel.

By following these steps and using the appropriate tools and materials, you can securely connect two fuel and pressure lines using a T-connector, ensuring a safe and reliable fuel system.

Oversized boat or plane tank

When it comes to choosing a fuel tank for your boat or plane, there are a variety of options available. The most suitable option will depend on the specific requirements and constraints of your vessel or aircraft. Here is an overview of some essential considerations and options for oversized boat or plane tanks:

Boat Fuel Tanks:

For boats, the two main types of fuel tanks are portable and permanent.

• Portable tanks are typically made of plastic and are designed to be easily removed, refilled, and replaced. They come in various sizes, ranging from one-gallon to fifty-gallon capacity. This option is ideal if you want the flexibility to remove and refill the tank yourself and if your boat has limited space for a large permanent tank.
• Permanent fuel tanks, on the other hand, are installed within the boat's hull and are not meant to be removed. These tanks are usually made of aluminum or plastic and can hold ten to several hundred gallons of fuel. They are more common on larger vessels, such as powerboats. If you opt for a permanent tank, careful planning and professional installation are crucial to ensure the tank's security and compliance with safety regulations.

When selecting a boat fuel tank, it is essential to consider your boat's fuel consumption, range requirements, and the space available for installation. Additionally, remember that a boat gas tank should never be completely filled. Best practice is to fill the tank to about 90% of its capacity to prevent over-pressurization and allow for fuel expansion.

Plane Fuel Tanks:

For aircraft, the three most popular fuel storage options are integral, bladder, and rigid removable fuel tanks.

• Rigid removable fuel tanks are commonly found in older aircraft and are made of materials like stainless steel or aluminum alloy to prevent leaks. They are supported by the airframe and secured with padded straps to prevent shifting during flight. These tanks are typically located in the wings and need to be securely fastened to the aircraft's structure.
• Integral fuel tanks are the lightest option and offer the most space per unit of weight. They are often positioned in the unused area inside the wings and require baffles to prevent fuel from splashing during aircraft maneuvers. Maintenance requires draining the fuel and following strict safety precautions, including respiratory protection and fuel vapour purification.
• Bladder tanks are made of reinforced flexible materials and share many characteristics with rigid tanks. They are easier to install as they don't need a large opening in the aircraft. Bladder tanks must be wrinkle-free to prevent fuel contaminants from settling in the fuel tank sump. They are used in aircraft of all sizes and offer strength, longevity, and a seamless design.

Consult with expert aviation welding technicians to learn more about the specific requirements and maintenance procedures for your aircraft's fuel tank.
