I fitted a remote oil filter last year and took the feed off the oil pump and through the sump. The return went back through the sump to feed the bearings. The picture shows the engine ready for bench testing just in case there was a problem, it is now back in the car and over 3000 miles so far. Oil pressure is a steady 50 psi with a fully reconditioned engine and uprated oil pump. Hope this is helpful.
