I'd say it's possible because the float often separates - but - most of the time, it sinks rather than bobs.

There is always an ingenious solution but, at least the obvious solution is nope. I had asked that question over here.

In fact, I have a brand new expansion tank sitting in my garage (along with the entire cooling system) just waiting for me to get a round tooit so I can start the job.

When I do, I will do an autopsy on the old expansion tank to see what it looks like. Instead of the transverse slices they did over in this autopsy, I will try a longitudinal slice to see how the float system works.
