What is the cause and cost to repair a Radiator leak looks like chocolate milk & strong fuel smell

175k, radiator leak on the driver side of the radiator looks like chocolate milk. Has been present for about 3 weeks. It just dumps out whenever I stop the car. Also have a VERY STRONG gasoline odor that is present when both driving and not driving the car. Has been present for about 4 months. There is a hose on the back top side of the engine that is wet with fuel. If I "gun" it when in neutral it sputters, but when driving it and I "gun" it to pass another car it doesn't sputter. No engine lights/codes coming on.

The issue is maybe not with the radiator, but the 'milk' appearance indicates that engine oil is mixing with coolant inside the engine. This often describes a cylinder head gasket leak - more serious than simply replacing the radiator. Have an inexpensive compression test performed to check for the engine sealing integrity.

The fuel smell and leak is resolved by replacing the leaking fuel line - fuel flexible hose. The parts are readily available; try these on-line sources; www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
