I will drop a cord into the tank to see if there is fuel in the tank tomorrow. A friend explained how to place an inline filter in the system and described it pretty much the same way that you did. I think that I will use your system to replace the "problematic" dual reservoir system. I use this truck as my daily driver so I have to wait until a good weekend where I can get all of the components together and have the time to follow your very nicely detailed instructions.
Thank You for your help.
With the Ford DFR system BOTH in-tank pumps must be functional. If not even a good DFR won't work correctly.
You probably won't be able to get a cord or anything into the tank unless you remove the entire filler hose. There is a smaller diameter air return hose inside the main filler hose. The tank has a metal cross hatch anti siphon device at the inlet that you would have a hard time getting anything larger than a drinking straw through.
