First a little back ground. A few years back, I bought a used 3250 watt Powermate generator. When I bought it, it had a crack in block, and a gas tank FULL of water. Replaced block and installed improved connecting rod. Earlier rods were prone to failure. Cleaned gas tank as I best could. Last fall just before hurricane Florence, repaired a hole in gas tank, using gas tank putty. Ran generator for a couple days during power outage. Afterwards, started smelling gas, so took tank off. Bottom was like Swiss cheese, full of small pin holes. Checked around for a replacement tank, but none were available. Replaced tank with a Septa 6 gallon under the seat marine tank. Fabricated some brackets to hold tank on top of generator where original tank had been. Added a "pulse fuel pump," as new tank had a top outlet. Left hose long, so I could remove tank from generator, and set on ground. This way, I could fuel generator while it was running without fear of spilling fuel on top of generator. Got to thinking about how to drain tank, when generator isn't in use. For generator, because of long run times, I use ethanol fuel as it's over a buck a gallon cheaper. Plus, I can return unused fuel to cans and run in truck. I added a quick disconnect to fuel line to allow me to drain tank into fuel can. The disconnect I used came from Bay Area Powersports ($10.95 shipped.) I ordered two so I could just connect fuel line from generator to line into gas can. Got me to thinking. If I could drain fuel back into can, why couldn't generator pick up fuel directly from fuel can. I had another can with same type cap, with a broken spout available as a parts donor. Using hole saw cut out a steel disk from a junk power washer frame, and ground it to fit inside the cap. Because the hole saw had a 1/4" pilot bit in it, disk already had a hole in center. Used a cut off bolt, and two nuts to make a mandrel to hold disk in drill, while using angle grinder to reduce it to needed size. Soldered a piece of 1/4" copper pipe into center hole of disk, with about 1" inch sticking out on each side of disk. Connected drain line to one side, using copper pipe as barb for fuel hose, slid disk inside extra cap, and added another piece of fuel line to other side to drop down to bottom of fuel can, for fuel pick up. Screwed disk assembly onto fuel can, and connected it to fuel line to generator. Opened vent hole of gas can and using mouth blew into can to force fuel into carb. Pulled starter rope, and off she went. FYI, fuel can was placed on ground, not elevated. So now, I can either use boat tank, or directly from fuel can, and I can take gas cans and fuel tank to gas station and fill all of them up, extending my run time.
