What should I be looking for in a fuel cell?

I came across a guy selling a 22 gallon steel fuel cell that came from a race car. The price is good and the cell looks like it is in good condition. I don't know very much about these things though. This particular one has only two fittings on the top (send and return?). It does not have a sender, is this something I can add? He didn't know if it had baffles, is this a problem or could I add fuel cell foam? I was always under the impression that fuel tanks were gravity fed, but the fittings are on toip, how does this work?
 
one for vent, one for return.
the vent at a minimum should have a rollover valve in it.
how does it fill?
It should have an outlet for the supply whether its on top for an in tank pickup or on the side close to the bottom, or a bottom sump type. You can add a level sender, but realize that if that tank has had fuel in it, it needs to be properly cleaned before cutting or welding on it. Foam baffling would be OK, I'm not to keen on it, what are the dimensions of it...any pics?
 
The cell has only the two fittings on top. I'm not sure what the proper nomenclature for the fill is but it has the twist off style cap on the top. I would guess it measures about 20x16x16ish and I spaced taking a pic when I was there.
 
Three reasons, first my truck currently only has one functioning saddle tank and believe it or not 11 gallons doesn't get you too far these days. Second, the way I am designing my flatbed the saddle tanks will be exposed. And third I want to keep the tank as far away from the rocks as possible.

Cool, I wasn't sure if it was going on a crawler, work truck, daily driver or what.

One word of advice is to stay away from the foam. Just let it slosh.
I've seen a lot of guys have problems with the foam deteriorating (quicker than you think too, not over a long period of time) and sucking chunks through their fuel filters and pumps.

My fuel cell is plumbed with feed and return lines and I drilled a hole and used a breather/rollover valve from Polyperformance. If you aren't allowed to vent into the atmosphere then you can get a bulkhead fitting and drill a new hole to install it and run it up to your charcoal canister.

This looks alot like the cell I was looking at, after a little reading I'm assuming it has some kind of bladder in it? Are there any reasons I shouldn't take this route? The only reason I assume it has a bladder is because of the bolt down top like the one in the pic. Also how would I go about adding a fuel level sender?
 
Yeah the part you're seeing is just the outside protective shell.

If you can figure out what fuel cell it is you can more than likely buy a sending unit to drop in. You want 0-90 ohm to work with your truck.
 
Well after doing some searching, by the time I do what I want I think I am better off just buying a new cell
 
Yes it comes with the bladder and ironically it is full of premium right now but Ill have to drain it to transport it back home
