Looking for Tips on building a fuel system

could always ditch the mechanical pump and run a Holley blue pump, have that in 2 cars. the coronets blue pump has been in there for 6 years and has seen a lot of street miles as well. as for the fuel line I'm not sure about the 5/16 line, I use 8an from cell to regulator. I think the braided line is much nicer and easier to run, not too expensive either. but would require you to weld a sump in your fuel tank. that would support your future HP goals as well
