Bob,
That is a great idea. If I understand correctly, I will hook the
oil pressure sender to the T as well as a single line feeding the Accusump. Can I use aluminum fittings for this? What size NPT is the block fitting - 1/4?
Roscoe,
Not exactly. I know my initial description of the setup is a little confusing. Let me try again. I am using a Mocal sandwich or collar between the block and the filter. This collar has two 1/2 fittings (one for the out line and one for the in line that run to the
oil cooler). The sandwich also has a built in thermostat so one does not have to use an inline thermostat like in your setup. If the
oil is not up to temperature, the oil flows from the block through the collar, through the filter, back through the collar and then back into the block. When the oil gets hot, it will flow through the collar to the filter and then gets routed to the cooler. Hence, when the oil is cool, it will completely bypass the cooler and there will be no pressure (or minimal) in the oil cooler and cooler lines. Now, if I plumb the Accusump into the oil cooler lines, the unit will disgorge its contents at start-up (pre-oiling). However, the Accusump will not fill back up until the oil gets hot enough to open the thermostat as there will be no pressure in the oil cooler lines until the thermostat opens. The result of this will be running 3 extra quarts (the capacity of the Accusump) of oil in the block until the oil gets hot enough, opens the thermostat and pressurizes the lines/Accusump. This is not a good thing right - running too much oil in the engine? Clear as Mud? I think Bob has provided the correct answer.
