Fuel Pressure Regulating Valve
An improperly operating fuel pressure regulating valve may cause high fuel temperature. If a problem is suspected, inspect the return fuel pressure regulating valve. Clean any contamination or debris that may keep the regulating valve from operating properly. If debris is present, find the source of the contamination. Replace the return fuel pressure regulating valve if the valve is worn or damaged.Fuel Level
Ensure that the fuel tank contains enough fuel. As the fuel tank level decreases, the fuel temperature generally increases. Fuel Lines
Restricted fuel return lines may produce very high fuel temperatures. Ensure that the fuel return flow to the fuel tank is not obstructed.Overheated Engine
The fuel is supplied to the injectors through a passage in the cylinder head. Abnormally high ambient air temperature could cause the fuel temperature to reach the trip level. An overheated engine could cause the fuel temperature to reach the trip level.
