Fuel cap for a 1925 Tudor

[jjarvi]

I have a 1925 T Tudor that is missing a gas cap. The tank appears original, a cap for it looks like it would be a push and twist type. There are no threads. All the caps I see for Model Ts on the supplier sites are screw on which is the same or very similar to my 26 T.
I've attached pictures of the tank. Does anyone recognize this? Is it likely that it's a replaced tank?
My father picked this car up in the early 60's from an estate sale, my older brothers tooled around in it until '67 or so and it sat until summer of '75 when my dad had it running again. It ran again in the summer of '83, now 39 years later we've got it running again. Before sealing the gas tank I'd like to make sure we can cap it.

Finding a cap may be a lost cause because the inlet neck on the tank appears to be broken. Something like this motorcycle cap may have worked by with only one peg hooked it may not seal well.

easy enough to replace the inlet, from a discarded tank, an get a proper cap to match

The piece that's sticking up is from some kind of accessory device. It should unscrew from the tank, leaving the standard threaded opening & allowing you to use a regular cap.

Thanks for the replies! I never noticed that it was broken. I'll check to see if it unscrews.
Thanks again!

I wonder if it has been soldered after screwing in place. I believe all tanks had the same threaded opening unless there were some different early versions.
If so be careful. I hope you have good results.

I've never seen a fitting like that on any old Ford. My guess is it's an accessory locking gas cap fitting. If it's made of brass, it might unscrew. If it's aluminum or pot metal, it may be stuck very tight. I would not put any heat on it. Solvent and penetrating oil might help loosen it. Applying pickling vinegar might be helpful. If all else fails, using a well-oiled hacksaw blade to saw it nearly through in three places, avoiding the threads, then carefully breaking it out with a light hammer and punch might work. I'm assuming it is actually screwed in to a standard Ford fitting, which seems very likely.

Since the neck is broken, finding a cap to fit would not solve the problem. I would suggest finding an old worn out tank of any type with an intact neck and cap. Carefully remove the neck from the Model T tank and the newly purchased tank and mount the replacement neck on the Model T tank. Jim Patrick

Jeffery, If you look close at the first picture or expand it out then you can see a couple of pins or possibly screws that have been filed off on the ramp part of the adapter, they are more than likely a locking feature. You might want to feel the underside to see it they protrude through to the inside of the tank. You may have to center-punch the pins and drill them out to remove the adapter. Jim

I blew up the photo as much as I could and I actually see three pins.
Two are readily visible, one is barely visible at 90° from the two that can be easily seen. It can barely be seen at the very surface level of the filler. I assume that there is a fourth pin located opposite of the one I just mentioned.
I'm going to make a guess, and this is ONLY A GUESS, that this non- stock filler was installed due to stripped or damaged threads in the filler.
My suggestion is to try and locate a replacement tank. They do show up from time to time here in the Parts For Sale section, or try and contact the vendors, such as Lang's, since they do stock parts that they don't normally advertise.

Good luck.
Mike.
