[urq] Pressure Accumulator substitution

[Louis-Alain Richard]

However, the ATF fluid in contact on the other side of the membrane is at
equal pressure (36-57 bar), and might "seal" the thing better than air from
atmospheric pressure.

That being said, if there was a problem sitting on the shelf, IMO the
manufacturer would have installed a sealed cap to prevent this behavior, an
easy and cheap preventive measure. And there would be a notice to 'splain
the stocking procedure. In an ideal world, at least :-).

Yes, they can go bad on the shelf.  The problem is that the pressurized gas
leaks through the membrane over time.  That said, having one unpressurized
on the shelf will last longer than a functional one in a car, where it
should normally be sitting at higher pressure pretty much constantly ...
