Could we get a screen cap and which mod pack you're using? It's much easier for us to help with your problem if we can see your exact set-up and we know what you have to work with.
If I'm feeling lazy, I'll run a straight line of stone pipes out from the quarry, and then line each side with at least iron chests. What I have noticed with that is the first chests in the line always seem to end up with the most in them. If I'm doing a big enough dig and I'm still feeling lazy enough to do the bare minimum, I set up a pipe from the chests that are first on the line that feed into another group of chests. Honestly, if you're at that point it really is worth investing the 2 diamonds in 8 diamond pipes so you can control things without baby-sitting the quarry.
