DIvided, that's really the same question.

airtrap = reservoir

At least that's my humble opionion. Check my sig for my "airtrap/reservoir". It's really worth it as you will have a good filling point and also a place to check your levels, and it's also very effective in getting the bubbles out of your system. You should place it just before the pump (at the suction end) so you can fill the line to the pump and cycle the pump on/off to fill the system, ok so I didn't place mine just before the pump but I will re-route my hoses some day and then I'll do that.
