Well i picked up my new/old 1996 Dodge 2500 Ram. Fuel gauge was at 1/4 full when picking it up so I bought some diesel conditioner & filled up the tank to the tune of $89 dollars, I took it that is was full. Driving home & waiting for the gauge to reach full, it never did. Hovered near half, then empty, then the low fuel light came on & so on.......It never reached full or stayed constant. Any known issues with this? I take it the gas sending unit/gauge/pump from a gaser would not be the same? Thanks
