The Traxxas Tmaxx 2.5 fuel tank comes with lines
The fuel tank is pressurized by the exhaust system to provide reliable fuel flow. The rubber seal on the fuel tank is important for the function of the engine. If the tank lid does not seal properly, an air leak may be created, which can cause the engine to run erratically and be difficult to start. The rubber O-ring tank seal can be adjusted for improved sealing by tightening the screw on the underside of the tank lid.
To fill the fuel bottle, squeeze the air out, insert the dispenser tip into the fuel can, and release your grip on the bottle. As the bottle expands, fuel will be drawn into it. To fill your model, flip up the spring-loaded cap on the fuel tank, insert the tip of the fuel bottle, and squeeze to dispense the fuel. Fill the tank until the fuel level reaches the base of the filler neck. Close the fuel tank lid, ensuring that it closes tightly.

The fuel feed and back pressure lines should be 9-10.5 inches long
The length of the fuel feed and back pressure lines is crucial for the optimal functioning of your RC vehicle. The ideal length for these lines falls within the range of 9 to 10.5 inches for each line. This measurement includes any additional length contributed by the fuel filter.
It is important to note that you can extend these lines slightly beyond the recommended range, up to approximately 11 inches or even a little more. This extended length provides a buffer, preventing the engine from stalling immediately when the RC vehicle flips over. However, it is important to consider the potential trade-off; longer fuel lines might cause fuel flow problems during standard operations.
The recommended length range of 9 to 10.5 inches strikes a balance between engine performance and fuel flow efficiency. This length ensures that the engine receives an adequate fuel supply during normal operations, and it also provides some leeway in the event of the vehicle flipping over, reducing the likelihood of immediate engine stalling.
When it comes to the routing of these fuel lines, personal preferences and practical considerations come into play. Some RC enthusiasts suggest routing the lines behind the cooling head, as this can help with fuel flow and engine temperature management. Ultimately, the routing decision depends on the specific design and configuration of your RC vehicle, so it's essential to refer to your vehicle's manual or seek advice from experienced hobbyists.
