I have two numbers here. One I know is for the
older vacuum apr and that number is 17113186.
As far as I can find out, this num has been
discontinued and a new number assigned,
but I'm not sure if this is a VAPR.

The new number is 12575028 and is listed at gm
parts direct as a fuel pressure regulator kit. I'm
hoping someone has already bought one and
can maybe confirm that is in fact a VAPR..

Thanks, Bob
