I have a 2002 altima that does not recirculate fuel back to the tank. There is no return line. I Notice sever millage differences in winter from summer. I know additives to gas are a contributing factor, but temperature also seems an inevitable culprit. I have created a device from a coil of copper tubing that incased inside a 3"copper chamber with reducers on both ends. I have it installed so the chamber is filled with coolant. And fuel can flow through the coil. I just have connected the fuel side. Maybe next winter.
I got scared. Anyone else try something like this. Any input would be appreciated.
