In my research I've stumbled on the in-tank setup from Tanks Inc (http://www.tanksinc.com/index.cfm/pa..._ID=6/art6.htm). Whether I use this or some other in-tank pump, I'll need to prep my original tank for the modification.

What needs to be done to safely cut, grind and weld on a factory tank? Does anyone have a writeup?

Let just say a new tank is cheap to start with... and much safer. But if you have to, a Good cleaning, flushing, and what every it take to remove all leftover gas and flumes...

Here is a link that someone publish of both bad and good methods.. But if it was me.. sell the old tank and buy a new one.

It looks like this article is cut off, there was more to it.

So maybe that helps less than I thought it would

I modified my old tank. New tanks for my car are NLA. There is really no danger as long as you keep air moving through it so no fumes accumulate. Air it out real well and leave a compressed air line in the tank during any welding/soldering operations and you will be good to go.

I did make the mistake of thinking the little bit of debris left in the tank wouldn't hurt anything. Not sure what I was thinking but I paid for that mistake. Ended up pulling the tank a second time and had a radiator shop acid wash the inside and reseal it. That only cost $100.

You could also use something like this to seal the tank after you complete all the cutting and welding http://www.eastwood.com/ew-gas-tank-...-for-cars.html, $50.
