new fuel tank options?

Can i have the input filler moved so that it is facing the tire instead of the fender well ?
Or is it something that requires fire and cutting and explosive ?
Or do they just fill it with water and do it ?

I do not know. Maybe someone else might know.

Not water, nitrogen. Dry ice is the easiest form of nitrogen for us laymen to acquire. You want to drain the tank completely, of course. Then fill with dry ice to suppress any remaining vapors, and displace oxygen. No oxygen, no boom.

Dry Ice is frozen carbon dioxide and should work.

Do you mean fill the entire 17 gallon tank with dry ice ?
Is that very hard to get and how expensive is that ?
In my conjectural case , could be 34 gallons possibly ?

I can buy it at my local groceries store. They sell by the pound. The last time I bought it (a couple of years ago) I believe I spent about $25.00 for 20 lbs. (2-10 lbs. pieces). I'm only guessing but I think 10 lbs. should do both tanks if you don't take too long to move the filler neck.

Note: Always wear heavy glove. Dry Ice is -271° C.

Another possibility is using Nitrogen. You can get a bottle and a regulator at your local welding shop, more expensive initially. Later you can use it to fill your tires.

In both cases be sure you use it in a well ventilated area, the gases will displace the oxygen in the air.

If you're talking about welding it with gas in it that's something that sounds kinda like a fun exercise, but it can be done. Welding it you'd fill it with Argon or Nitrogen via a welding tank full of that stuff. Then you'd do your welding after making sure all your buddies are far, far away.

The easiest thing to do is wait till the tank is low, pull it and drain it. Don't put the last 1/4 gallon of gas in the tank in the grass or the flowerbed. That'll just be against EPA regulations and you know how bad it is to be against the EPA. They get all twisted up. The only way you'd be able to get away with that is to do it and not tell anyone. Oh wait....

Anyway, with the tank empty just rinse it out with water a couple of times and let it air dry. Tank is no longer explosive, weld however you want. Then put it back in, fill tank, drive away.

Just water ? What about all that stuff about dry ice ?

You don't need dry ice or nitrogen/argon if there's no gas around to blow up. It's just a steel box without the gas. But again just make sure to let it air dry in the sun to prevent rust.
Oh, and you'll probably want to put some tank liner in while you have them out for longevity. Por15 makes some that's not too expensive. Heck, I'd go ahead and por-15 the outside, line the inside, and make em all purty before I put 'em in! That'd be sweet!

Hey - you are right !
Especially if its full of water - the cutting and welding could all be done with the greatest of ease :-)

Further -
Now that I bought an newly rebuilt 350 thats gonna go in - I was thinking of putting in an whole Holley "Sniper" EFI .
BUT NOW I realized my financial situation ( tax season )!
So I will probably just use my original cab gas tank for now until the summer arrives ( when my biz always picks up ) and then I can do all this work with the side tanks .
That means I will use an mech fuel pump ( for now just to get it running ) and an rebuilt Edelbrock 350 carb I'll get from an friend for $100
Is the tank guy still out there ?
