Fuel Lines

This is a mercury outboard fuel line coming apart from the inside, which will clog fuel pumps and carburetors.

Fuel lines that are showing deterioration on the outside are deteriorated on the inside too. Marine grade line holds up a little better than regular stuff, but too many variables. One big thing is if your premix 2 stroke, or just straight gas running through the lines. If you have any type of rubber debris in your filter or carb bowls its probably time already. Premix in the lines can swell inner liner and cause flow issues.
