Do you guys think the best engine oil ports to use for the Pre-Oiler / Back-Up Oil Pump are the 2 ports on the oil filter housing that were intended for Bypass Oil Filter installation? I would like to avoid adding a shut-off solenoid in line with the Pre-Oiler / Back-Up Oil Pump
I need some clarification, if the pump spins freely when it is not powered, it would allow oil to bypass the oil filter and return unfiltered to the engine, right? I don't understand how the bypass part of the Oil Filter Housing works... if a hose were connected to the 2 oil ports on the housing(hose port to port), would the oil flow unrestricted thru the hose all the time and very little would go thru the higher resistance oil filter? Is there a Bypass Valve somewhere in there?
An updated lubricating oil filter bypass valve is available for certain ISX engines (does this valve control flow thru the Oil Filter Housing Bypass Oil Filter Ports?) https://quickserve.cummins.com/bpv/index.html
Here you go, maybe this will help (Huge THANKS to Daniel Babbitt for the videos)
