I know any way I do it will work, but maybe aeration was not the correct term to use. I am thinking more about aromatics. I just cringe when I go to my friends and see all their gas cans open. I was just thinking that the splashing fuel coming in from the top fitting may release a lot of the fuels aromatic/vapors out the vent there by decreasing the grade of the fuel quicker. Pretty knit picky thing but since this project is taking forever I might as well do it the best I can. I appreciate your experience, perspectives and advice. Thanks, Jim
