Fuel Valve/Fuel Lines

inspect, allow the engine and exhaust
system to cool completely. Open the hood and inspect the muffler and
pipes for cracks or damage. Check for weak or missing retaining
springs or damper/support grommets.

allowing adequate time for the exhaust system to cool. Exhaust
system temperatures can exceed 900° F (500° C). Never
perform this procedure with the engine running or shortly after it’s
been running.
