Marine-grade fuel lines are different from automotive fuel lines in several ways. Marine fuel lines have better UV and flame resistance, and are low permeation, which is an EPA regulation that doesn't apply to cars. They also have a different fire rating and are designed to protect against the line breaking down from ethanol. Marine fuel lines are more expensive than automotive fuel lines, which are rated E85 and twice the line at a fraction of the cost.
| Characteristics | Values |
|---|---|
| UV resistance | Marine fuel lines have better UV resistance as they are exposed to direct daylight |
| Flame resistance | Marine fuel lines have better flame resistance |
| Burn-through properties | Marine fuel lines have specific burn-through properties, meaning it takes a certain amount of time for a fire to burn through the hose |
| Fire rating | Marine fuel lines have a different fire rating to automotive fuel lines |
| Low permeation | Marine fuel lines are "low permeation" due to EPA regulations |
| Ethanol protection | Marine fuel lines protect against the line breaking down from ethanol |
| Cost | Automotive fuel lines are twice the line at a fraction of the cost of marine fuel lines |

Marine fuel lines have a different fire rating
Automotive fuel lines are exposed to virtually no daylight and therefore do not need UV protection. They are also e85 rated and twice the line at a fraction of the cost.
Marine grade fuel lines are also designed to protect against the line breaking down from ethanol. However, they have a pesky liner that needs to be watched out for.
It is important to use the correct type of fuel line for your vehicle or boat. While some people may choose to use automotive fuel lines for their boats, this is not recommended by professionals.

Marine fuel lines protect against the line breaking down from ethanol
Marine grade fuel lines are designed to protect against the line breaking down from ethanol. They are also flame resistant, with a specific burn-through time, and have better UV resistance than automotive fuel lines. Marine fuel lines are also "low permeation", which is an EPA regulation that does not apply to cars.
Automotive fuel lines are exposed to little to no direct daylight, so they do not require UV protection. They are also e85 rated, which means they are twice the line at a fraction of the cost of marine fuel lines.
