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.
• Every few years, remove and inspect exhaust manifold for corrosion.
• Clean and tighten electrical connections, ends of battery cables. Wire-brush battery terminals & fill cells with distilled water.
• Inspect bilge blower hose for leaks.
