my "plan" :poke: was to use the original feed as the return as I have already ran a new 3/8 line from the tank to the pump. I got a new sending unit that is 3/8 feed so I'll run a hose from the old feed to the return on the new sending unit. I guess I'll cap off the other tank line that ran to the charcoal cannister which has been put in the Round file :glasses2:
