There are two versions. http://enginegearonline.com/gepuforoilfu.html Same pump head, but one has a larger motor. For the small amount of oil you will circulate, the smaller one will be fine. But again, it is an electric motor, and sooner or later they may fail? Get a second opinion from Rusty too :) Buly On 6/16/05 2:46 PM, "Bob White" wrote: > Hi Buly, > > I have a sort of unique situation that wouldn't apply to most anyone > else.
