Car leaking gas..... :(

Just when I thought it couldn't get any worse....


Came home today to find my car leaking gas down the driveway. My uncle checked it out and said there's a hole. Man....my dad's pissed....we can't get it fixed til Monday. But I'm going away Monday...so my brother's saying we can't get it fixed til Thursday when I get back. Bah!!!! 🙁

:Q

Where's the leak nativesunshine, the tank itself or somewhere along the fuel lines?
 
JB Weld works good on gas tanks....either that or duct tape...cause duct tape rocks!

So does coathangers on exhaust systems. (yes this is a sarcastic remark)


 
I have welded many diesel fuel tanks, taking proper precautions and sweating profusely, but I would not advise, under ANY circumstances, welding a gas tank unless that is your professional specialty and have all the proper equipment.
 
Gas tanks are welde three ways:

1. Fill with water and weld. I would think this would cause problems drying it out and rust.

2. Fill with gasoline and weld. I would never do this. I've been told it's a common way to do it, but if someone I knew would try it, I wouldn't be around to witness it.

3. Fill with inert gas and weld. Probably the safest/most practical way. Nitrogen or helium would work. I've heard of ducting exhaust from a running vehicle into them.
 
there are gas tank repair kits around for $10. it's a two part putty that you mush together and then smear over the hole. i've never tried it but it's worth a shot
 
You could probably find out where exactly it is by lighting a match, the fire will take the trail right to the source of the explosion -I mean leak. 😉

How have you managed to live this long with advice like that ?
 
ive also heard that as a way to do it...

Please explain the reasoning behind this, gasoline in any form is extremely volatile, filling the tank with gasoline and then welding the tank will cause a fireball and mushroom cloud.

Anyone for russian roulette ?

I think the "I wouldn't be around to witness it" comment pretty much sums up how he's managed to live this long...

I certainly agree that an expert should do this, just as a response to the extremely volatile comment, gasonline in liquid form is much more stable than vapor.

It's a good thing the users of this forum are intelligent, otherwise I can actually see someone taking such advice and running w/ it! 😛

I watched a guy do this once, the tank exploded blowing him across the shop and it knocked over the torch set braking the oxygen tank valve and launch this across the shop the other way like a missile. It stopped after making a hole in the side of the building a wedging it's self under a car. No one was seriously hurt.

I would think gas would cause duct tape to come apart

You sir are correct 😉 😛

I think for now, this is the best way to go. Or, you could siphon the gas out of your tank and put it into another vehicle before it all leaks on the driveway.

Is the physical tank itself leaking, or just one of the gas line fittings or tubes?

 
This thread definately isn't one of the brighter ones in recent weeks...:Q

My question is.. how did the hole get in your tank in the first place? Did it like rust through or something? lol

I'm assuming so. I don't know much about cars and my dad didn't tell me anything. I'm wondering about that too...how the hold got there.

and I agree..some of the suggestions are quite....

In theory that is correct.

Gasoline can only burn within certain concentrations of vapour in air. These are called the lower explosive limit (LEL) and upper explosive limit (UEL). The LEL and UEL of gasoline are approx 1.4% and 7.6%. Any mixture of air containing less then 1.4% gasoline vapor is 'too lean' to burn and greater than 7.6% is 'too rich' to ignite. So in theory with a full tank the mixture is too rich and will not burn. But I still would not like to be around to see someone weld that way as even the slightest leak will create a pocket of flamable mixture at some point which can easily ignite.

Filling with inert gas works by removing oxygen as an air mixture with less than 8% O2 cannot support combustion.
