Gas tank filler lock fell into the gas tank!

I was finally able to use a screwdriver to pry the shell off my locking gas cap that was frozen. I got the shell off but the lock mechanism actually fell into the gas tank. I bought some magnets on a expandable shaft and put it down the neck to try and use the magnet to catch the lock. But there seems to be a baffle at the base of the filler tube. My question;is there a baffle inside the tank that might protect the sender unit from being struck by this lock floating around in the gas tank. I pulled the gas tank before when I put in a new sender unit and I don't remember seeing any baffles. Is there a way I can avoid pulling the tank to get that lock mechanism out. Or, is it okay just to leave it in. I don't want it to damage that new sender unit. But I'm guess I'm preparing for the worst. I'm beginning to think the only way to get the lock mechanism out is to drop the tank and remove the sender unit so there's a nice big hole I can put my hand in.

There is no reason I can think of to cause an issue just leaving the unit in the tank. They are usually mostly brass so a magnet will not likely work. The pick-up tube is 5/16" OD so there is no way the unit will interfere with gas flow. If you do drop the tank you can likely just jiggle it around to get the unit back out through the filler neck. Up to you.

As to whether it can roll around and do damage I could not say if there is enough weight behind it but I expect it would take quite a bit of force from acceleration or braking or even turns for it to move that hard. Unless the tank is near empty and float is hanging close to the bottom there is not much else for it to hit. Noise from the lock banging on a side or knocking any old rust flakes off might be the more prevalent complaint.

Here are photos of the inside of a 47 and 48 tank posted a few years ago. I don't remember who took the 48 but I believe the 47 photos were supplied by Wes Boyer.

Thank you for giving me some peace of mind. I don't drive the car hard enough to sling the lock around in the tank. After all, the car is more of a place than a thing on the road. In a recent ride, my cousin who drives a Corvette, was stunned such a large machine could go down the road so majestically. But,it is a Packard!

The lock cylinder won't be buoyant in gasoline. It's unlikely to even move in normal driving. If you keep the tank decently full then there's no way it would touch the float aside from the most absurd of circumstances.

'55 400. Needs aesthetic parts put back on, and electrical system sorted.
'55 Clipper Deluxe. Engine is stuck-ish.

I'm not sure they are magnetic either. I don't recall them being brass, maybe white/pot metal? I have one somewhere.
When I tried to clean out the gunk in the tank, I had a difficult time removing what I put in to scour the interior. So not unexpected, but patience and craft may help. I'd drain the tank of all the gas. There should be a drain plug on it, but maybe frozen so don't heat or over power.
Then you might fish a stout wire down and get the lock near the drain and snag with the wire through the fill tube, but just guessing. A flexible inspection camera would help too in fishing it out.
If you drop the tank you should be able to take it out through the level gauge opening. Probably your best shot*.
I wouldn't approach this by taking off the top cover. These are fairly non-robust and you can usually force them off. That's how I got mine off. Brute force.
Probably not the first. I don't know if it will or won't do damage, but why take the chance? I can see it both ways.
* I just changed the fuel gauge on my diesel P/U and the plastic/metal inlet screen broke off in several pieces and impacted the sending unit. I tried to pull it all out with my flexible grabber, but couldn't get the last small one. So I had to go in with my arm through the gauge hole.

If you're not having fun, maybe it's your own damned fault.
