How are the electrics different? They were used interchangeably on T1 and T3 cars so the resistance range should be the same. The big deal with the cylindrical senders was mostly in the shape of the tank they fit into and how they worked. Because of the shape, they would only move within a specifically placed column of fuel, which restricted the float movement as opposed to the long-arm-float model. The Type 3 tank had the sender position off-set a tad from the sedan version, allowing the sender to extend down vertically into the tank well at about the mid-point of the tank (left/right). Bill Drayer has been running one of the cylindrical senders in his wide CMC (I think he has 914 gauges, IIRC) for over a decade with no issues. I have no input as to whether the cylindrical sender will provide a smoother gauge needle action. The latency (float) of the sedan gas gauge had more to do with the averaging of the sender signal by using a "damper" in the sender wire at the gauge and that gizmo served to damp the signal and make the needle slower moving (it averaged the signal amplitude from the sender). The cylinder sender worked similarly, but did it in a mechanical manner without use of an electrical "damper". Again - they should be interchangeable if you don't use a "damper".
*****EDIT**** OK, so the site auto-corrects when I use what it thinks are "naughty bits". The above has been edited without the naughty bits and might not make quite as much sense, now. Sorry
The "damper" is called an "exciter" (AKA "vibrat0r"). There has been discussion about adapting one to a 914 gauge, but the consensus here is no.
Ah, HA!
Ed found the "naughty bit" filter, too! He's a clever character manipulator, though, and got around it. I'll be he goes way back to the "Adventure" days of "XYZZY", too (follow the Plovers!).
I shall not comment on the definition, though. Don't want the "Naughty Bit" daemon after me.
@EDSNOVA : While walking around the EPCOT Flower and Garden show a few weeks back (in between sieges of pneumonia) I spotted a guy wearing this Tee-Shirt:

I have to get one of those..........
The tube sender provides damping since the fuel in the tube flows in and out through small openings.
Here is information about types of gauge mechanisms and senders:

Thanks Michael. Great article. The design certainly makes more sense to me.
here's a good article on a mod to the sender. did this on my bus and it worked great:

as for inter-operability - check the resistance with a multi-meter
Great!
