accusump question

from engine to oil cooler, oil cooler to remote oil filter (ford type with return flow inhibitor) to engine block. The accusump is plugged in the line after the oil filter and before it goes into the block.

Steady 25 psi. I was just doing startup tuning a couple of days ago and it never dropped below 25 psi despite it sometimes took me quite a while before restarting the engine.
Oil pressure does fluctuate somewhat after starting which is normal as it refills, but never goes below 35-40 psi when idling.

I have been thinking about having the electric valve controlled by the ecu to fine tune its behavior. Just haven't gotten around to it as I have more important things to deal with and it functions ok as it is.

That's how it is plumbed mine too, but i was thinking about moving it BEFORE the oil filter to get filtered everything out of it to the block. Yes, in this way Accusump will be unfiltered

any oil that is in the accusump has to pass through the filter and for that reason is already filtered prior to entering. I don't see the problem.

I'm worried for all the parts in the Accusump system (tanl, epc valve, pipes, hose ends) that could contaminate the oil with particles in case of a failure.
Yes, probably, overrating it

If cleaned properly prior to install, there shouldn't be a worry imo.

The accusump has moving parts so there will be wear and debris, albeit not much. If I was doing one from scratch, the filter would be at the end. I wouldn't change a working setup if that was the only thing I didn't like.

Internally it has an o-ring. It's not like it's going to create metal shavings.

yes a one way valve is needed, I have tested all kinds of diff ways to do this with the oil pan off,yes off. made a hell of a mess

Thanks

Depends where you plumb it and what filter you use. I use a ford filter that is build not to have oil backflowing. So I don't need a one way valve (which restricts flow btw)

on the bb fords we plum them into the rear of the engine, NOT the spot by the filter< in this spot it fills the filter,and goes to the oil pump first before any bearing sees oil. In the rear it goes to the rear first then forward to lifters ect.. if you have an ext filter we always install a 1 way valve,so it goes to the engine,and not in the hose going to the filter, same on ext oil pump.
