Default refueling my RV12

I'm tired of hauling 5 gallon cans of gas. My airport car is a 2001 Chrysler van has a 20 gallon gas tank and internal pump that can put out 5 GPM. Is it a pipe dream to try to tap into it?

Not a pipe dream, but a slightly better option is to build a “portable unit”.

I got a 30 gallon fuel tank out of a junk yard. It had the pump internal to the tank (I think it was a Chevy tahoe). I simply put handles on it and made up a power wire to my 12V on the truck, added a static wire and booyah , a fuel transfer tank for not much money.

You could technically put it in the trunk of a car, but you might want to check your local laws. Or go roque

I'm using an old race car fuel cell bladder (ATL). Find some local race car shops and they will probably have some old ones laying around. You want the black hard plastic bladder. Northern tool sells a small 12v transfer pump with all the hoses and a gas station style filler nozzle for $100.00. It says diesel only but they have to say that. I use a large funnel with an automotive paint strainer into the tank.

I use a light weight industrial push kart with the fuel cell on the top and the 12v battery and a charger on the bottom.

The top shelf on the push kart lines up well with the tail gate on the pickup so I can side the cell into the truck bed with minimal strain

Next time I go to the AP I'll take a picture.

I'd use a little caution here... "diesel only" means just that. There are similar style pumps made specifically for gasoline.

Just saying...

Down right scary what you folks are doing to save a few cents on fuel.
Just saying...
I started out hauling fuel around until certified 91 UL melted a piston. It's just not worth the risk to the engine or the plane in case of a fire.

Wait, what melted a piston?

The only fuel on field is leaded avgas, so I keep three 5 gallon plastic gas cans in the back of the truck. It's less than a mile from the gas station selling ethanol-free premium to the hangar. I've briefly considered a larger container, but I don't like the thought of hauling gasoline around any more than necessary. The guy I bought the plane from had a 15 gallon fuel can with a 2-wheel cart and pump... definitely not worth the hassle of getting something like that in and out of my pickup bed.

The reason some transfer pumps say "diesel only" is that many of them are lubricated by the "oil" in diesel. Gasoline lacks this lubricating quality causing the pump to fail prematurely.

Usually its the type of seals used and gas will cause them to swell and fail.
Used to work on diesel and gas engines have found out along with hydraulic seals the same.

I use a fuel transport system designed for sports enthusiasts (boaters, race cars, etc.) I have no financial interest or affiliation with the company, but think that their system works well.

I have 2 red transport jugs of 8 gal each and 1 hand cranked fuel pump that screws into each jug. I drive to the gas station, and purchase 16 gal of premium pump gas and drive back to the airport. I attach the pump and manually fill my tank in about 5 min of easy cranking. Put everything away, go fly!

There are other, more likely, causes of a melted piston than using unleaded fuel recommended by Rotax: incorrect ignition timing, mechanical problems, oil lubrication problems, incorrect prop pitch.
