Cobra29 had questions regarding the "Preluber". I purchased the model that can be set to turn on and run after engine shutoff. The preluber supplies 55-60 lbs. of
oil pressure while running. The control can be set anywhere from 0-6 minutes to help prevent hot
oil from "coking" on metal surfaces. There is a concern expressed by the Accusump people that because the Preluber draws
oil directly from the oil pan that dirty unfiltered oil is sent into the engine. This is only true IF the unit is plumbed into the oil pressure sending unit port. If the unit is plumbed into the oil cooler return line all oil is filtered prior to entering the engine. Remember, even the oil pump itself draws unfiltered oil from the pan and sends it to the filter before the oil gets to the engine. The preluber merely replaces the oil pump for a few seconds as a pressurization device. In reality, the Preluber takes up less space than the Accusump and can be used in addition during an oil change to purge the oil cooler and hoses which are not usually drained during a normal oil change.
Since I run a T-sump road racing style pan I added a second drain plug to drain oil from since the Preluber replaces the original drain plug with a special fitting adapter. That way I avoided having to use the quick disconnect fitting on the suction hose as specified in the instructions supplied with the Preluber. Accusumps end up costing about the same as the Prlubers once you add the tank, brackets, electric solenoid switch, valve, and plumbing. The Preluber comes with everything you need in the kit. The only thing you may have to swap out is the oil pan adapter fitting. Preluber has fittings to fit most if not all applications for around $20. I have been very satisfied with this setup.
