Brake fluid reservoir float?

If there is a will, there is a way.

I vaguely recall a similar side-of-the-road project and recollect that the two-part epoxy failed to adhere to the plastic float. There were other issues at play (loss of fluid), but after hard use, the epoxy seemed loose enough to suggest the fix was temporary. Per your explanation, perhaps the epoxy had not fully cured or the plastic float was not properly cleaned. I recall consideration of a suitably sized and shaped float, allowing a fastener to pass through to the float bottom.

Keep your eye on eBay- they “pop-up” on a regular basis.

If just the rubber has perished and the float is still sealed, I'd suggest you repair the original as I outlined several posts above. JB Weld and an aluminum rivet will work very well. I did this repair almost 2 months ago and it is still intact. JB Weld will not be impacted by brake fluid.
 
It’s all about the distance from the cap to the bottom of the float.
Different tanks have different heights and therefore different caps with floats.
