Well Tom, I can only tell you what I have heard. At
one point I had the idea to replace the stock 14 Gal.
fuel tank in my 98 RC with the larger 21 Gal. fuel
tank from another Dakota that had the larger fuel tank
as an option. I talked with a stealer mechanic friend
that told me that I would need to make sure I got the
in tank assembly from the donor truck as well as the
tank as I would need all the internals to make my fuel
gauge rear correctly. I think (and I know what you're
saying, there he goes thinking again!) the intank fuel
pump/sending unit runs thru the PCM to generate a
signal to drive the gauge. Don't know for sure and I
don't know if this helps but hope so.
