You can use lengths of standard brake line also. Most stores carry it in five foot lengths, so a junction will be needed in the middle. Just cut one end off and slip the hose on. There's no pressure on the suction side unless you have a rear mounted electric pump. I'm running EFI with 39 psi on the lines, so I put a little silicone on the end and push the rubber hose about an inch up -- enough to get two clamps on. Never had a leak, though two clamps might be a little over kill. Better over kill than killed though...
