The other day I weighed at the elevator, filled full with fuel and water then weighed again. Empty and 1/4 tank of fuel was 27,860 w/ me in it, Full of fuel and water was 80,020 (Legal is 80k flat). Considering we'll rarely run it plumb full of fuel and it's only 20 lbs, I consider that a success.
Pics of the tank and the pump setup:


Bottom joint is for the fill, it takes 20 minutes to load the tank at the co-op, and 40 to unload at home (restricted by the 2" hose at home)

Motor is a GX200 Honda, starts first pull every time and burns almost no gas. As much as I love American stuff, even my Briggs and Stratton-die-hard HS Ag teacher agreed that the new Hondas are far superior to B&S. He even said the Honda knock-offs are better than B&S....

The rubber isolators you see are slices of an endlink bushing off the SSEi.
