Milky diesel fuel is often a sign of water contamination. Water can enter the fuel system through condensation, leaks, or poorly sealed caps, leading to the formation of an emulsion that looks milky. This contamination can cause significant damage to your fuel injection system and engine. To solve this problem, drain the contaminated fuel and replace it with fresh diesel. Additionally, inspect your fuel storage practices and equipment for leaks or sources of water ingress to prevent future occurrences.
