And here is the answer to my email:
Marty, the Model 25-4CV is the Spinner model for your pickup. The installation has merit, although there is work required to initially install one of these. The problem is that the Model 25-4CV is a gravity drain unit so the return oil needs to be returned to an atmospheric oil pressure point on the engine block or pan. On the 5. 9, the usual method is to modify the turbo oil return piping to incorporate another pipe to return the Spinner's oil to. Also, the Spinner requires a horizontal mount as well as an oil supply hose. The oil supply is not a problem, there is an oil supply port on the oil filter head designed for this purpose. Cummins requires a 30 psi low oil pressure cut-out valve for any bypass oil filtration device attached to the 5. 9. The Model 25-4CV incorporates this device internally so it meets Cummins requirements. The cost of the Model 25-4CV is $US252. 56. This amount includes UPS ground freight to anywhere in North America. Payment by credit card is accepted by Visa, Mastercard and American Express.
Thanks for your inquiry, Sean Aughey, Oiltech
