I did a quick and dirty install today.

Im getting 55 PSI of oil pressure with key one (before crank).

the book says it takes 30 seconds to bleed all the oil out of the tank (looks more like 20 to me).

but it works.

basically sounds like a warmed up engine at crank.

If I were to do this over again, I would get 2 small ones instead of 1 large one. I have to move my oil bypass and coolant filter to make room for this torpedo to fit under the pax area chasis side.

if you already have an oil by pass filter, you can t off the oil cap hole. if not, you could buy the oil filter cap with the threaded hole. or, you could pull the oil pressure sensor and install a t there.

The T fitting is at the oil filter cap. One line for the preluber, the other for the oil by pass filter.

I need to move my coolant filter and out l bypass filter so I can move the preluber tank there under pax chassis position. Too nice of a day today to mess with that though.

I don't see a pump unless I missed it. So what draws the oil from the pre lube tank to the engine? And how does the pre lube tank get refilled after shutdown? Sorry for the ignorance.

In theory - The tank is pressurized with oil as the motor runs, check valve. Then prior to starting the motor, a solenoid opens to release the pressure from the tank back into the motor. You just have to add enough oil to the system to prime the tank and hose once. I would imagine that there is an air pocket in the tank to support pressurization.

I got it. Thank you. I am a little dense up top when it comes to these things. A neat product, can differently see where it could be benafical especially in colder climates.

When the tank is installed...you add 10 to 20 psi of air.

when the engine runs, a check valves goes one way and that fills the tank at the highest psi the engine generated. For the 6.4 that’s about 55 to 60 psi.

when you shut the engine off, the one way check valve keeps the tank pressurized.

key on but before crank, check cabled becomes two way valve and oil is injected into engine at the highest psi that was generated at last run. It can maintain this for 20 seconds .

so after 5 seconds of key on, the engine has been preluber...I crank the engine. Engine as engine cranks the psi is maintained.

30 seconds after key on, check valve becomes one way again.

one way check valve stores the highest psi the engine generates.

the flow rate is about 2 gallons per minute with the model d tank which holds about 5qts.
