ls1 fuel sending unit. I'm working on a 67 nova. It's a ground up build. my issue is my fuel lines. I had an complete fuel tank from an 01 trans am. I made a alum fuel cell and cnc a mount for top of of it and inserted the unit in the top. Worked out really well. My issues is plumbing it. I know the feed line. But what are the other 3 lines. One appears to be the return. But I thought everything was built in to the tank. So how should my fuel line be ran. I saw a link to I believe vetted works where they came out of the feed then put a tee in it. The brand ran to the rail and the other one to the return pipe on tank. But the sending unit is different than mine. Mine has 2 lines that come out and shot left. One 3/8 and one is 5/16. Then 2 go straight and are 5/16
