348 Gas Tank Baffles and Solutions

Check for post by Ernie who had the same issue. He was able to find a specialist to weld the interior baffle and make leak repairs, but this is done with unit out of the car. Alternatively, you can look for a replacement used part.

 

Yeah pull it out of the car and take it to a specialist in tank repair. They will purge it and weld it up. Pretty easy fix.
Not something to try of you never did it before

 

Or you could take it to an amateur and set up a video camera

 

LOL. Next contender for a Darwin Award!!!

 

I do a lot, including welding, but this tank welding is a job I would leave to someone else, stand back 200ft, and get my iphone on record mode.

 

You'll likely have more luck looking in Toronto or Montreal I would think

 

Hold my Beer !!!

 

Almost blew myself up welding a friends oil pan (still on the car and flushed out with lacquer thinner). Well it did explode but not enough for anything to go flying. Pan probably had another 1/2 qt capacity from it being bowed out in every dimension.

As for the tanks, I empty and after a day of leaving it open, flush out with water. I then hook up a tube from my cars exhaust to the tank and let exhaust run through the tank for a few hours. (evaporating the rest of the fuel and flushing out any remaining fumes).

Have not had a problem doing that but still cringe the first time I strike an arc

 

LOL

Lacquer thinner the virgin stuff is explosive big time
We used to take the 5 gallon cans put 1 gallon in them, tap a spark plug into the top, let sit in sun a wee bit and fire it with a condenser. It was how I teach my guys to be careful in the shop.
So when I was on vacation they did it with a 16 gallon drum, bunch of smart ass's, the mushroom cloud caught the attention of the police for sure LOL

 

You effing maniac...

I used to have a chemistry professor who … on the first day of class would bring down a balloon of hydrogen and oxygen and then light a match to demonstrate how making water can be explosive. He would then increase the size of the balloons. By the time he got to the 50 gallon size balloons, all the students cleared the room.

I don't think that flies anymore.

 

I removed an oil tank from an VW, then took it off the car to a professional welder and paid him $20 for tig welding. No explosion, thank you very much.
You know, people forget how much energy is available in a gallon of gas... when it lets go with a boom.

 

Yeah reminds me of we used to fill balloons with acetylene ox and tie them to helium balloons with a fuse. I had 1 guy was addicted to it. Heres a video of what happens not what we did no cams back them

 

They also forgot how much energy is in 5 gallons of gas, and a quarter stick of dynamite

 

Now we know other pyros LOL

 

Lmao, good times

 

As Vince said, my old tank had the internal baffles pop off the spot welds. One of the welds pulled out of the bottom of the tank which resulted in a severe gas leak. I after washing the tank out with water, I left it sit for a few weeks in the hot sun, open, to evaporate as much of the fumes from the tank as possible. I found a welder who cut open a flap in the bottom and welded up the tank. He used rosette welds because they are stronger compared to the spot welds the factory used.

That tank eventually got crushed and replaced with a used tank.

 

Somebody did something similar, but with a plastic milk carton and a plug from a beetle; new underwear for the driver of the beatle!!!!

 

Thanks for the update.

 

My Chemistry professor did this on the first day of class as well. So it still flies, at least in the south. He did a demonstration at an open house and lit about 10 balloons at once. It set off many car alarms in the parking lot haha.
