Fill it with water first to evacuate the fumes.

Dry Ice works better! I used to remove Old underground fuel tanks from gas stations and you weren't allowed to transport them unless the fumes were evacuated with Dry Ice then you could cut the tank in half

You can also use argon or car exhaust.

So I have read about these.

I need to grind flat and then weld a patch.

Do I need the inert gas in there while I grind/weld or do I just put a bunch in there, wait, and then all the bad stuff is cleared out and I don’t need to worry?
Kinda nervous

If it were me I would first rinse with something that gasoline is soluble in and that is also soluble in water (gasoline is not soluble in water). Acetone or alcohol come to mind. Rinse out the gasoline with one of those and then rinse the tank with water. You could then purge with an inert gas to remove the oxygen if you're still nervous.

works too . Purge before grinding. Do it on the front lawn, not inside.

 

[J Mack]

Just purge with CO2 and weld what you need, as our friend B0B said dry ice is the best most efficient way to do what you're asking.

Bob getting kinky again!

Yeah, be sure to get all the gas out first. A rinse out would be a good idea, or let it sit open for several days so everything can completely evaporate out. Stick your line into the tank coming from your oxygen displacing gas of choice and then yes, let it run in there for several minutes before making sparks and then leave it on the entire time you do the work and while it cools.

SORRY

 

[xtiaan2000]

I am going to blast this thing for a day or two w a shop vac and then get some dry ice and weld this thing up!

 

[xtiaan2000]

Okay! I didn’t blow up!

Gave it a couple days with a bunch of hours with a shop vac blowing into it.
Boy, I’ll tell you I was really tempted to put a match up to it! The first night! Something’s wrong with me.
I waited and got lazy.
No dry ice.
No exhaust piping.
Put a paper on a broom stick and……..
Nothing.
Game on!
Filled two old send and return holes.
Made a new ‘hat’ for the pump and gauge. Welded it in.
Made a little strap thing to hold tank down to the carriage.
Welded brackets for the carriage to the frame. Old tank used to hang on the bed sheet metal. :/

Now painting tank. ‘Blue by you’

Pics to come.

That's one way of doing it!

 

[xtiaan2000]

Had a mask on too!

 

[xtiaan2000]

Little high but, Dig the look!

 

[xtiaan2000]

Finally got my clutch master and slave. Gonna flare the new tubes and get back to Rush55!

Pics still to come.

 

[xtiaan2000]

My fuel gauge sender was in with sheet metal screws and always leaked. So I got to practice with my buddies plasma cutter and welded some nuts to make for a tighter seal and hopefully stop that leak.

Always looking for the chance to practice!

Had to move the gauge sender and put the pump in but the access panel did not line up. There is a cross member on the 80 frame that moved the tank back. Closed off the old hole and created two new ones that I hope now are accessible through the hatch. Did some measuring so I hope it now lines up.

Welded two brackets to hold the tank to the cradle.

And painted.

 

[xtiaan2000]

Got that fuel pump/bracket from mr Mosely.

 

[xtiaan2000]

I think that I will just cap the 4 tubes that go to the vapor thing. See if I can go without. Trying to limit the whole stinky cab thing.

Thoughts?
