Additionally, silicone fuel lines or clear fuel lines are suitable replacements for cracked fuel lines. It is also important to ensure that the fuel lines are compatible with the type of fuel being used, as certain fuel additives, such as ethanol (E10), can have a detrimental effect on rubber, causing the lines to become gooey and melted.
Furthermore, braided steel and rubber lines, such as Russell's premade lines, are also an option and are expected to last around 3 years. While these lines may be more expensive, they offer increased durability and safety. Ultimately, the longevity of fuel hoses depends on various factors, including the type of hose, the operating pressure, and the fuel quality. Regular inspections and maintenance by a professional mechanic are crucial to ensure the safety and functionality of your vehicle's fuel system.
In summary, rubber fuel lines should be replaced every 10 to 15 years, or earlier if weather cracking is observed. By staying vigilant and proactive, you can help ensure the safe and efficient operation of your vehicle's fuel system.

E10 fuel can have a detrimental effect on certain types of rubber
The lifespan of a rubber fuel line varies, with some lasting 30-40 years and others perishing within a year. However, it is generally recommended to replace rubber fuel lines every 10-15 years or whenever any signs of weather cracking are noted. This is because, over time, rubber fuel lines can become soft and gummy or hard and cracked, leading to fuel leaks and other issues.
One factor that can significantly impact the lifespan of rubber fuel lines is the type of fuel used. With the recent introduction of E10 fuel, concerns have been raised about its potential detrimental effects on certain types of rubber. E10 fuel contains a higher concentration of ethanol (up to 10%) compared to the previous E5 standard, which typically contained only 2-3% ethanol.
Ethanol is a solvent that can eat through rubber, causing hoses and seals to perish more quickly. This can lead to fuel leaks, blocked fuel filters, damaged fuel pumps, and other issues. The Department for Transport tests identified degradation to fuel hoses and seals, blocked fuel filters, damaged fuel pumps, corroded carbs, blocked injectors, and corrosion in fuel tanks as problems associated with E10 fuel.
Additionally, ethanol is hygroscopic, meaning it absorbs water from the atmosphere, which can lead to condensation in fuel tanks, fuel lines, and carburettors. This condensation can then cause corrosion in brass, copper, lead, tin, and zinc components. As a result, it is recommended that owners of older vehicles, particularly those manufactured before 2002, avoid using E10 fuel and opt for E5 or "pure" petrol instead.
To mitigate the potential detrimental effects of E10 fuel on rubber fuel lines, some preventative measures can be taken. These include using ethanol-friendly materials, such as those listed by the Federation of British Historic Vehicle Clubs (FBHVC), and regularly checking fuel lines for any signs of wear and fatigue. In some cases, it may be necessary to replace rubber fuel lines with more durable options, such as teflon-lined braided stainless steel hoses, to ensure compatibility with E10 fuel and prevent costly repairs.

Braided steel and rubber hoses should last longer than 3 years
Rubber fuel lines have a recommended replacement period of 10 to 15 years, but their lifespan can vary greatly, with some hoses lasting only a year and others persisting for 30 to 40 years. This variability is due to several factors, including the hose's exposure to environmental conditions like temperature fluctuations, weather, and road contaminants.
Braided steel and rubber hoses, however, are designed to offer enhanced durability and longevity compared to standard rubber hoses. These hybrid hoses combine the flexibility of rubber with the strength and protection of braided steel. The steel braiding acts as a physical barrier, guarding the inner rubber hose from external damage, abrasion, and corrosion.
The steel braiding also provides structural reinforcement, allowing the hose to withstand higher pressures and resist kinking or collapsing. This is especially beneficial in plumbing applications, where braided steel hoses can endure higher water pressure and maintain better water flow than their rubber counterparts.
Additionally, braided steel hoses are less susceptible to the detrimental effects of heat, water, and chemicals that often cause rubber hoses to leak or burst. This increased resistance to degradation results in a longer lifespan for braided steel and rubber hoses.
While the exact lifespan of braided steel and rubber hoses will depend on various factors, including the frequency and intensity of use, exposure to extreme conditions, and the quality of the hose, they are generally expected to last longer than three years. Proper installation, maintenance, and regular inspections will also contribute to the longevity of these hoses.
