Extending the lines to put the tank in the bed....

What size of rubber fuel lines do I need? (the two that run along the frame rail and go directly to the tank)

5/16" or 3/8" i.d.??????????:icon_confused:

Ford has always used 1/4 for the return and 5/16 for the supply in their fuel injected cars and trucks. You may be referring to the vent line instead of the fuel return but you've got me on that one.

And make sure you get the proper rubber line if you have fuel injection.

That is important. In any state where you have any sort of safety inspections it isn't legal to run non-FI rubber hose in a fuel injection setup. Even if you don't have an SI program, it isn't safe. Real easy to blow a line out.
