My fittings arrived to finish the plumbing and install of my Frantz Oil Refiner bypass system on my 22RE powered 4Runner.
Oil supply comes from the block via a 1/8 BSP to -4AN fitting to a -4AN line to a tee fitting on the inlet of the filter. One side of the tee feeds pressure to the filter and the other side continues on to an Autometer and OEM pressure sender. Outlet of the filter is also plumbed in -4AN to a return on the cylinder head in the fuel pump block off plate that I drilled and tapped for 1/8 NPT and fitted with a -4AN to 1/8" NPT fitting.
I drew a sample after adding the required makeup oil to the system to have a baseline prior to running the system. I will run this until the filter stops flowing and draw a sample prior to changing the filter and diluting with fresh top up oil.
Haven't driven the system much yet but idle pressure is down about 2 psi and in town cruise oil pressure is down 5-8 psi according to my Autometer gauge. It still has plenty of oil pressure to be safe and I haven't been on the highway yet to evaluate. I don't expect highway oil pressure to be affected since it previously went down the highway on the oil pump bypass at 75-80 psi.
Current filter media is Scott 1000 at 74 cents per element.
