Narrative:
During walk around inspection; I immediately noticed fuel dripping from the #1 engine drain line and a pool of fuel on the ground. Inspected the #1 engine bay and found the entire engine and engine bay covered in a thin coating of fuel. Primarily; fuel on the forward part of engine bay; accessory section and fuel heavier on the engine bay deck. Mechanic arrived and found the #1 engine main fuel line connection loose at the FCU (fuel contol unit). Main fuel line connections have eyelets for safety wire to secure connections in place and prevent 'backing off.' present maintenance procedures do not install safety wire to these connections. Request safety wire be installed to all engine fuel and oil line connections for a safety and security of these connections. Furthermore; engine fuel and oil connections are not marked with slip mark paint for visual inspection of safety and security of the connections and/or if they are marked. Request application of slip mark paint to all engine fuel and oil connections.
