anyone know what size fuel hose I should use for a 1990 merc v-200. I just bought this boat, right now theirs two 12g tanks with larger hoses 7/16" or so im guessing connected to a two way, so you switch to one tank then the other. Then the main line going to the ball, and through the motor which is 5/16". Ive read a few things saying you should have 3/8" hose to the ball then 5/16 after that. Any thoughts on this. Im just not sure if 5/16 is big enough or how the taper down hoses work. thx, :confused:
