I am thinking about adding a fuel transfer tank on my F-350 flatbed for the use of filling up mowers and 5 gal mixed gas tanks. I have seen the ones on northern tool and was wondering if that was the best way to go, or are their other options, practicalities that are better. Also, does anyone here have something like this setup and what time savings does it provide. Last year, I was at the gas station daily filling up the 10gal TT and everyother day filling 5gal mixed gas. Real pain, especially in mid day, so what size would you consider, the F-350 is diesel so it dosen't need filling but 1-2 week.
