I have a quick question folks. I launched my boat late this year (July 15, 2016) and will pull it out of the water on November 8, 2016. This is my first year with this boat. Prior to launching this year, I replaced my primary Groco filter with a Racor 120 housing/ 10 micron filter, I changed my facet electric fuel pump filter, and installed a new Universal secondary filter. My diesel ran great this year but I have only put about 10 hours on it and consumed 4 gallons of diesel fuel all season. Is it really necessary to change all of the fuel filters again with so few hours of engine time? I do plan to change the oil and oil filter.
