Finished up the fuel system. I used 1/2 hard tubing for the supply and 3/8 for the return. Replaced the original 5/16th sending unit with a new 3/8 sending unit. I cut the sock filter off the end and connected this to the return line. I mounted the factory Duramax fuel cooler in the return line. For now I skipped the dual filters and lift pump and went directly to the stock engine mounted filter. To connect the new lines to the engine. I cut the flex tubing with quick connectors off of the factory lines. slid the flex line over my new hard line and hose clamped them.
