I just read a commentcomment by @RussellBorogove about the Apollo 11 abort options that the landing module had about 700 pounds of fuel left on touchdown. I assume that this is the intended behavior for any detached craft (you probably always plan in a little reserve that you do not want to use up), I wonder if it is generally possible to use that leftover fuel in the next stage:

In an Apollo-style mission, can you recover leftover fuel from the descent stage for the ascent stage and from the ascent stage for the command module? I.e. can you pump it from the earlier stages to the current stage? Did the Apollo missions do that or did they leave fuel on the moon (and whereever the ascent module went)?

Can landing modules use left over fuel from earlier stages?
