I agree. What makes you think you need an electric pump?
Mechanical pump easily replaced at any parts store. Does not need wiring, mounting brackets, oil pressure safety switch, or plumbing revisions and is quiet.
This is the pump I have used on a few of my projects. Nice and quiet and never left me sitting. Price is right also. Airtex e8251 It is a Marine pump. 30 GPH which should support around 350HP. http://www.ebay.com/sch/i.html?_from=R40...51&_sacat=0
