If you use the smallest avalible fuel tank from a 92-96 4 cyl Dakota it is like a fuel cell you can put in the trunk. That way you can adapt the factory fuel pump, you will have to make the lines from scratch. You can also make the fuel filler tube work with some mods. Don't forget to pull the intake manifold and replace the belly pan gasket on the bottom. Get the updated gasket from the dealer, if you don't they are known to suck/burn oil.
