Temporary run gas can

I've got an old boat gas can in the scrap pile right now and now you have me thinking. A low pressure pump in that could be great for priming stuff with carbs that was winterized. Especially anything with a pull cord! It could maybe even be a standard priming bulb like what comes on boat cans.

What about a water filled fire extinguisher. You know the ones you charge with air. Fill with gas charge hook to carb.

This seems inherently wrong to me. Sure, it can be labeled, but the cost of a mistake could be very high, even deadly.

I do think that basic concept works with a garden sprayer, but it may not take long for gas to start eating parts.

Another idea is to put a tire valve stem into a gas can and pressurize it with a tire pump, garden sprayer, or regulated shop air. I have some plastic cans with valve stems in them for vents (no schrader) and the seal seems to work fine. You could even put an air regulator right on the can and have semi-regulated fuel pressure anywhere you have compressed air. Any guesses on whether a metal gas can is OK with 60psi?

I've got a ~100 gallon semitruck tank that I have a Schrader in. It's not as fast as a gas station fill pump, but it will push out 15 gallons in maybe five minutes through a 3/4" hose and nozzle. The cap vents pretty low, I doubt it gets above 5PSI.

Got one of the little Ryobi 18V compressors that has adjustable pressure shut off, I used that this year. Worked good, but apparently the little bit of rain it saw did something and made it run incessantly as long as a battery was in it. I'll try another one again next year perhaps.

Same thing happened to my rigid pump.
A little rain is all it took
 
Yeah, I had purchased it within 30 days, was able to return it without problem. Basically I got to use it for free. About the only reason I need one of these things (although I think my new shop compressor failed too) so I probably won't pick another one up until I need to actually use it again.

The digital displays, settings, and what not are pretty cool, but I'm guessing they have no sort of protection from water and resulting corrosion allows contact to be made when nothing has been pressed. I left it indoors to dry for a few days, made no difference.

Kind of a funny story, I had used the compressor during the day, thrown it back in the truck, and hours later walked back out to the truck to get something. I heard something running, and I thought "oh no, I left the heater on!". Since the fuse panel melted I've got the heater on 12V battery until I re-do everything. Get up to the truck and to my relief, it was the compressor which had turned itself on. It had been running long enough to almost kill a fresh 4aH battery, which I assume had been hours with no load. Duty cycle on these I believe is 5 minutes lol.

Not as cool obviously, but apparently the inside threads of the Scepter fuel cans are the same as 2"(?) threaded PVC. Not sure if any of the PVC options play well with anything other than diesel, but there are enough PVC plugs and caps that you can build pretty much anything you'd likely need with those. I'll probably use one of the PVC bits to add a pickup tube/hose for my diesel heater.

You know- I think those threads are intended to fit the old metal screw in pour spouts for the metal Jerry cans. Not sure about PVC fittings though.
