Sorry for the poor image above but this it the Cracked Fuel Line I'm trying to show
Fuel Lines rarely need replacement, but over time rubber begin to age and harden, developing cracks and leaks. When they begin to go bad, the results can be catastropic. Vibrations, Rubbing against other components, or impact can all cause an old line to rupture or crack, leading to engine fires or fuel starvation. Check all fuel lines, for stress fractures or corrosion. The image above was the cracked fuel line from an '05 STI with less than 9656.064 km ( 6000 miles )on the odometer.
