Fuel injectors seldom leak, but their rubber components are susceptible to corrosion and breakage. Fuel tank leaks are easily detected as gasoline spots on the pavement and appear as a rusty, corroded, weeping tear or puncture hole in a gas tank. Rubber fuel lines are a common leak source, as they are highly susceptible to the corrosive effects of gasoline, weather and road debris.
