General Engines and Fuel Systems

• Inspect fuel lines, including fill and vent hoses, for softness, brittleness or cracking
• Check all joints for leaks and make sure all lines are well supported with non-combustible clips or straps with smooth edges
• Inspect fuel tanks, fuel pumps and filters for leaks. Clamps should be snug and free of rust. Clean fuel filters.
• Inspect cooling hoses and fittings for stiffness, rot, leaks and/or cracking. Make sure they fit snugly and are double-clamped.
