My 68 was originally 6 cyl with 5/16 fuel line. I put in a beefed up 350 and had a little problem with the rubber hose from steel line to pump which is 3/8. I just had to tighten the hose real tight. Now I see the line is badly bent up in places. Can I replace the entire line from tank with 3/8 line for SB I see at Rick's? Will I have to change anything at the tank like the Sending unit? I see 3/8 sending unit but I'm hoping to use my existing one since it works fine.
