Inline remote oil filters, scavenge side Options

[iamchappy]

I am installing a Canton remote oil filter in between my oil tank and the engine scavenge inlet. I am doing this to eliminate the possibility of metal particles that have showed up in the past on the sump screen. There may have been some lurking in the tank or lines that never flushed out.
? what size filter would be adequate to filter and not hinder oil flow, a fine element 8-micron or a fine 140 mesh 150 micron screen, the oil pump is a turbo pump.

I use a Canton filter on the scavenge side of my 914/6 track car. I do not use a stock tank in my car (so no built in filter there). I think of this filter as having two purposes:
1. catch garbage that comes out of the engine so it doesn't pollute the tank, cooler, etc.
2. I use the mesh screen filter, so it serves as a convenient inspection filter (easier than the Canton disposable filter elements).

As for flow, I believe I remember that when I bought mine 10+ years ago, Canton rated its filters at something like 40 gallons per minute of 180 degree oil in the large filters (not distinguishing between the coarse and fine filters, interestingly). This is way more than any 911 engine will need, so you're good there.
