[urq] Pressure Accumulator substitution

[Ben Swann]

Awhile back there was a post about a source for a pressure accumulator (aka. Bomb) that
is used on one of the BMWs and is nearly identical to the one used in the Ur Quattro.  I
looked at it at the time and it appeared to be identical.  However, now I’m not locating
the information.

Anyone recall this and the source?
