GM part for aux pump? / Rebuit accumulator?

[Leah and David Mueller]

I lost my files from a computor crash, so I apologize for this question.  I
do remember that there had been some discussion regarding  a GM alternative
to the after run turbo pump?  Also, how has the rebuilt accumulator
experiement worked out?  Somebody had tried to put in new valves and
recharged them as I recall?

Thanks , and any more fading light thoughts?
