Bill--

Nice looking installation! Thanks for the photos and the advice.  I am assuming that this pump is a special order since I'm unable to decipher some of the part number:

108 = 108 Series
AM = Series Wound DC Motor
S = Standard Temperature Rating
32 = Pump Size (.0321 CIPR)
C = Reservoir Size (46 cu.in - 26 cu.in useable)
ZZ = UNKNOWN Circuit Configuration
3 = 1/8" Pipe Ports
V = Vertical Mount
14 = High Pressure Relief Valve Setting (1400 PSI)
08 = Low Pressure Relief Valve Setting (800 PSI)
Y = UNKNOWN

I guess I'll have to whip out my credit card and buy a new pump. May I ask where you bought yours?
