removed both powerpole pumps and purged lines. The "Max/Min" capacity lines on the reservoir are very faint so I took a sharpie and filled it. I did not want to fill with fluid prior to reinstalling for fear of spilling fluid. So, now that I have them installed, I cannot see the aforementioned lines. Does anyone know the fluid capacity of these reservoirs? I have googled with no luck. Next step, ask JL Marine. Great customer service. Thanks.
