That is certainly the normal and easiest way to connect an accusump,
but not necessarily the best. Supplying oil directly to the oil
galleries seems to have substantially improved the reliability and
lifespan of my engines--it means my engines always have at least 50 or
more pounds of pressure in the oil gallery--even at startup.
Not only is the plumbing greatly simplified, but in measuring the
gallery oil pressure on my TR3 engine I still saw great variation in
pressure with RPM that you don't see with the accusump directly
connected. I could come up with lots of scenarios that would cut oil
pressure with an accusump connected to a remote filter or cooler line,
but only one with a direct gallery connection.
Bottom line, if you're going to go to the expense and added
complication of using an accusump you should get the most value out of
it. Going through an oil filter adapter plate doesn't seem to do that
for me. I'd like to protect against catastrophes like having that
filter rupture or come unscrewed and still having bearing oil pressure
long enough to get the motor shut down.
