The new boat has dual imco saddle tanks....the dipshit I bought it from had a 5/16 rubber line coming from each tank into a manual selector valve, then a single 3/8" feed from there to the mechanical pump. I'd like to not run a manual selector. I would like to either run both tanks together or a remote actuated selector. Any good electric tank selectors out there with big holes in 'em?
Also, line sizes...will a -8 feed support 800hp?
