I am getting ready to mount tank and run fuel lines. I have some 6AN hose and fittings. I am going to use the stock fuel tank and looking at the lines coming out it’s going to be a PITA to get it over the fuel supply line. My question is 6 an good enough for a 400 hp engine? I can get 8 an but it’s pretty expensive and already have the 6. The car will be a cruiser but may hit the local strip a time or two.
