Toilet Prank Worked on BX25

[AStanton]

I recently did the 300-hour service on my Kubota BX25. I agonized over how to change the fuel filters without losing a boatload of diesel fuel. Some guys talked about plugging the vent holes on the cap, while others installed a shut off valve. I then got to thinking about the old toilet bowl prank: you cover the bowl with a taut sheet of Saran Wrap and wait for the victim. I decided to do this to the opening of the fuel tank. Simply remove the cap, apply a piece of wrap, then tighten the cap lightly down with the wrap extending over the threads. It worked for me. With almost 3 gallons of fuel in the tank, I lost only about a half pint of fuel during the filter change.

OMG.. learn something new every day.. My tractor has a shut of valve, but in reference to the toilet bowl prank, I had never heard of that.. geez.. that sounds ..uh.. messy, maybe even unsanitary oh, boy..

Nice trick, I may use it. I wonder if it would work just as well or even better if the tank were full? Could you test that out and let us know?

I have been using a similar version of this when removing my push mower blade.

I unscrew the gas cap and use an old plastic grocery bag over the opening, tighten cap and you can now tip mower over on its side without a nasty gasoline mess

I was unfarmiliar with that toilet prank (though, very farmiliar with the one where you tip over an occupied porta-potty) , but I have someone in mind to try it out on.

Who is going to clean up after that prank?

Many years ago there was an Ozzie bloke called 'Gelignite' Jack Murry. Used to compete in the Round Australia car trials. His party trick was to throw a stick of gelignite down the long drop toilet. One time, at a local fair he got a very long fuse, threw it down the dunny and then went and sought out the local cop. "Wasn't me officer I was over the other side of the fair talking to you when it went up"

It would work even better with a full tank because there is less air space in the tank hence less volume to create a vacuum in.

Great tip!

Nope.

A full tank will drain down until it reaches a point where the force of the fuel pushing down into the line is reasonably well-balanced against the force of the air pushing up through the line trying to enter the tank. There's an equilibrium point somewhere where the fuel should slow to a very slow drip and not increase in flow. You won't get it to completely stop.

This will happen with all liquids, in all airtight containers, providing that the exit line is sufficiently small for the viscosity of the liquid.
