I just want to make sure I am understanding the fuel system correctly for my 2006 Duramax. I installed a dual lift pump setup (Kennedy), along with a Nicktane pre-filter setup in the rear next to the fuel tank, as well as the Nicktane setup in the front replacing the OEM filter (Both 2 micron spin on HE filters). While my truck is running at idle, my lift pumps continuously pump fuel through the lines and through the fuel rail. If it is not needed, the extra fuel runs back into the tank, and that makes a continuous circle over and over again. Am I correct in this understanding of how the fuel system works? So in theory, the fuel gets continuously filtered over and over again, constantly running through the filters? Thank you in advance for your help in this fuel related matter.
