Carl,
I was thinking the same thing! We are only measuring Full and Empty, and everything in between.
But,
FIG. 12 (Standard Range Tank) Item -17.....Transmitter....0426517-1
FIG. 13 (Long Range Tank) item -14 .....Transmitter........0426517-2
So, according to the Parts Manual there is at least a slight difference.
I would call MacFarlane anyways and ask.
