Home Made Gas Pump

I have one of these:


The problem is the crappy pump handle and hose broke a long time ago. Even if it hadn't, it would have taken about 5 years to fuel up my truck one squeeze at a time. I replaced the line with rubber fuel hose and added a brass valve and fitting, but now this fuel caddy only works via gravity. That's fine if I'm fueling up my lawnmower, but if I wanted to top off my truck before a trail run that means I have to find something taller than my fuel door to sit this unit on. Loaded with a full 14 gallons of gas makes this a heavy beast to pick up that high.

Most of the fuel transfer pumps that I see (both hand or electric powered) say they are only for diesel. The ones that say they are rated for gasoline are usually in the $300 range.

One possible solution I've dreamed up is to rig a low pressure, high flow air pump to pressurize the top of the tank which in theory would force the gasoline out of the bottom fitting and through the hose into the vehicle. My concern with this is that I'm pretty sure this gas caddy was not meant to be a pressure vessel and I'm afraid of what would happen if 14 gallons of pressurized petroleum ruptured all over my garage.

Any thoughts or other possible solutions?

While something I thought of, it needs to be portable. It already comes with hard plastic wheels which don't roll very well. I was thinking of buying a cheap dolly with pneumatic tires from Harbor Freight to strap the tank/pump/12V battery to. This would also give me the ability to ground any mechanical or electrical components I use to prevent static discharge.

You could just siphon it.$2 for a hose long enough and possibly some gas in your mouth.

For a siphon to work the end point must be a lower elevation than the draw point which means I would still need to lift the gas caddy above the level of the fuel door.

What about a cheap inline fuel pump from a local auto parts store? I would imagine it wouldn't be too hard to mount it down by the petcock, you would just need to get creative with how to hook it up to the lines. Gravity would feed the pump and then it would push it out the hose. Also would probably need something to protect it slightly from getting damaged since it would be sticking off the caddy. unless you used some sort of quick connects.

An in-line fuel pump like a Walbro was another option I was considering. The drawback is the flow rate. Most of them max out in the 250L/Hr rate, which equals about 1GPM. That means it would take almost 15 minutes to empty the caddy.
