I need to replace my fuel pump and housing assembly in my 1997 4.0 TJ sport (export spec) . On RockAuto they list 19 and 15 gal ones. Does anyone know if the difference is just in the calibration of the fuel gauge sender unit?
I’m in the UK and my original tank was removed to make room for a LPG cylinder. A smaller aftermarket 5 gal gas tank was fitted under the LH seat.
