The fuel line on a Honda motorcycle is an important component that ensures the efficient delivery of fuel to the engine. While there are different models of Honda motorcycles, with varying specifications, one of the most commonly discussed fuel line sizes for Honda motorcycles is 5.5mm, which is often described as a stock size for many of the Honda twins and singles produced in the 1960s to 1980s. This size is also mentioned by owners of specific models like the 1985 Honda CB450SC and the 1974 CB360.

What You'll Learn
The fuel line on a 1985 Honda CB450SC is likely 1/4 inch or 5/16ths of an inch
The fuel line on a Honda motorcycle is an important component that requires regular maintenance and, at times, replacement. Over time, fuel lines can become brittle, cracked, or clogged, leading to fuel leaks or restricted fuel flow, which can cause performance issues or even safety hazards.
For owners of the 1985 Honda CB450SC, finding the correct fuel line size can be a challenge. While the official part number is available, specific dimensions are often not listed, leading to confusion and difficulty in sourcing replacements. In such cases, it is essential to have accurate information to ensure the proper functioning and safety of the motorcycle.
Based on the available information, it is likely that the fuel line on a 1985 Honda CB450SC is either 1/4 inch or 5/16ths of an inch in diameter. This estimation is supported by the experiences of other Honda motorcycle owners who have encountered similar challenges in identifying the correct fuel line size for their vehicles.
While a 1/4-inch fuel line may be slightly loose, it can still be used effectively with proper clamping. On the other hand, a 3/16-inch fuel line may be too tight and difficult to install without clamps. Therefore, it is recommended to opt for the slightly larger size to ensure a secure fit, especially if you have limited access to clamps or prefer a more straightforward installation process.
Additionally, it is worth noting that the standard Honda fuel line size for many models is 5.5mm, which falls between the two sizes mentioned above. This size can be sourced from various retailers, including Honda dealers and online stores, ensuring compatibility and a proper fit for your 1985 Honda CB450SC.
