Fuel leak under tank

It's basic chemistry, something you two obviously knows nothing about.

I'm more concerned about the physics of drilling into a tank full of liquid with a drill bit. For some reason the principles of an Archimedes screw combined with the sparking brushes of an electrical motor come to mind. But hey, what could possibly go wrong...
 
Interestingly, it doesn't drip anymore (and it's not because it's empty, the tank was full this morning)

So I'm a bit lost....

Anyway, it will go to the garage on monday. I plan a big trip with that car and I'm concerned.

Are you sure it's the tank itself that's leaking, it's usually the hoses and the joints on the filter that leaks. I suspect it will leak again if you start the car and the fuel pump starts working.

If you can see where it's leaking from get a bar of soap and firmly rub it over the hole, soap goes into the hole and plugs it. Yes, it works. You can then get it repaired properly, although I drove for years on a soap plug.

It's not going to catch fire from a drip. I would even drive it.

Liquid soap ?

Nothing really, as long as an expert in basic chemistry performs this delicate task.

Had something like that some time ago on my Corsa, drove around with the car some time as I also thought it was a tank that's leaking, only to find that one side of the fuel lines has somehow disconnected from the fuel filter, snapped it back on, problem solved.

I think we should shoot the vehicle into space, where there is a vacuum....summon the guardians of the galaxy. Groot will install a temporary plug while Rocket repairs it with his laser welder. Quill will play some soothing music while we wait, and Gomora can dance for us

The bar of soap (Sunlight) is a quick repair trick that has been done a zillion times in the past AND IT WORKS.
It's been tried and tested over and over.

Hello everybody

I just noticed that my Land Cruiser 80 (from 1996) has a fuel leak. It's dripping from under the tank and smelling petrol.

It's friday evening and I don't think it's a good idea to drive the car. What do you recommend? Leave the car where it is and tow it to my mechanic on monday?

thanks...

Some friends of mine hit a rock that caused a fuel tank leak once. The AA driver that came out used that epoxy-putty similar to this to seal the leak. They waited for it to dry and were fine for the rest of the trip.

Drill into a leaking petrol tank? Have you seen what goes on inside an electric drill?

Ask Magnum, he is the master in basic chemistry, only someone like him should be allowed to drill into a tank full of petrol.

Fill tank with water...Then you can do anything to it without fire...

How far did you drive after filling? If only a very short distance it might be that the tank was overfilled and the increase of the day temperature expanded the volume of fuel in the tank and thus spilled out of the overflow valve.

Good point.

Wow. You are insane. Clinically. Nuts.
Drilling around petrol fumes?

I'm surprised you have lived this long.

I like to think he was being sarcastic.
