I'd just go for the No on the auto fan option. Make sure they have good return policies when buying parts like this. They may have consolidated the books down. I'd cross reference to make sure they aren't trying to sell you a generation II pump!

They're showing some listings, but are asking me about "auto fan" versions of the pump. Apparently the "auto fan" parts come in two "hub heights" - 2 11/16" and 3". The "w/o auto fan" version does not specify this height. Help! Wth do I need? I'm pretty sure I don't have an auto fan, though I don't know for sure what it is. Does it mean one with a thermostatic clutch? I hate it when these guys throw weird sidewinders like this. thx.mch. jl _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
