Fleshing out the pre-oiler (pump version) concept:

Pump: http://www.ebay.com/itm/NEW-Heavy-Du...0f353e&vxp=mtr
Pressure Switch: http://www.omega.com/Pressure/pdf/PSW-190.pdf
Check Valve: http://www.northerntool.com/shop/too...5615_200335615

I'd envision a feed from the oil pan to the pump, then check valve, then pressure switch, then feed to the oil filter. The system could be totally automatic, with the pressure switch engaging the pump whenever the pressure dropped below a set pressure (eg 30 psi). I know this is not a new concept, but I wonder how it compares operationally (and ease of install) to the accusump. All said I think it's more compact than the accusump, and would provide a steady oil pressure / feed rather than a single shot. Thoughts?
