I just installed A PM full flow filter. The machining of the 3rd pice is very easy, chips and shavings were not a problem, probably spent 10 minutes off the engine including setup and cutting. . Do get a new case gasket.
If the authenticity police don't like the filter, get some pre A, copper Schrader valve caps for the rear tires, that will catch their eye and they will never see the filter.

Regarding the screws holding the cover plate, you could always substitute them with hex head bolts if the screw heads get too scuffed up to use a screwdriver.
The PM unit is very sturdy and has not had any damage from the occasional bump. An added benefit that I don't think has been mentioned is that the engine oil is cooler as the unit is in the wind stream. The full flow plus the aluminum oil cooler keeps my engine much cooler regardless of the ambient temperature.
If someone has the full flow mounted remotely, it would be good info to see the installation, etc.

I notice you have a remote alternative that's a little less expensive. Is that easier to install? or is the oil pump mod requirement still there?

Chuck, that Remote Adapter installs on the engine just like the Full Flow does, but then you have to add the hoses, fitting, etc.
And, yes that was a Pre Mat Full Flow John fitted.
Regarding the screws, they are #8 and there is sufficient material there to go up to #10s if the threads end up buggered.
If going the remote route, with hoses, be very careful of routing. A friend had one too close to muffler and it melted the inner rubber. Fortunately caught it before it blew, but cost him a day on his trip to overnite an new hose.

I know of a fresh engine with Scat, Carrillo, Shasta parts that went bang because of that. Summit and others sell ultra high temp hose covers to protect the hoses. Buy some.

When using the remote full flow filter, is the mounting location critical, that is, should it also be as low as possible and, is a modification to the oil pump gears needed due to the addition of the oil lines (greater distance = greater pressure needed?).
Mike; the oil pump gears are capable of much more than we ask of them; MUCH more.
On our race cars, we pump to the front of the car for the filter, then two coolers, then back to the engine; no problem.

Second what Vic says regarding the pump; that sucker's nearly the size of a SBC pump which has, what, 10-times the bearing area? I think the factory did that so when the bearing wore out from the crummy filtration, the thing would STILL hold pressure.
Anyhow, here's a link to an old article, but it's still valid. The last page covers design considerations: https://precisionmatters.biz/pdf/full-f ... ration.pdf
