What is your opinion of, or, better yet, experience with, using a non EPA (i.e. fully vented, unpressurized) portable fuel tank with a modern, 4-stroke outboard (in the case, a Tohatsu 9.8)? I would like to use a metal, OMC 6 gal tank w/ my new O/B. I feel like I should be able to piece together a hose with an OMC fitting on the tank end and Tohatsu fitting on the O/B end and a modern squeeze bulb in the middle, and it "should" work with the tank vented during operation. Has anyone done this? What are your thoughts?
