There may be differences between the plastic tanks. So make your own measurements. My tank doesn't have the left side fittings for a saddle. So that is one difference.
The only real way to tell is to drive until the light goes on and the suck the rest out through the fuel line. Perhaps setting the vehicle to a 15-20 degree tilt beforehand to give a margin of safety. Restarting a dry diesel is no fun, especially so for the newer ones like mine that don't have a hand operated primer.
