Can you give me the year of your Silverado and what engine you have? And are you sure of the name 'hot fuel module'? There are fuel pump control modules, fuel composition modules, etc.

Ya, that's it, sorry, the composition tester module.

Ok, the fuel composition sensor, also called Flexible Fuel Sensor, is located on the frame rail under the truck. Follow the fuel line from the gas tank forward and you'll see it. It's a small metal box that has an inlet and outlet fuel line on it and one connector. Very easy to replace if that's what you need to do.
