I took the on-engine filters and pitched them, then I added a Racor 500 with a 2 micron element, attached to the bulkhead because I didn't know if Racor rated their filters for vibration. 2 switchable Racor primaries and one Racor secondary. I put 2 microns in all of them (bought a case).
I also had some custom oil hoses made up and flipped the oil filter over. Every start, I got virtually instant oil pressure, plus it didn't p*ss oil everywhere when I changed it.
half price through a tractor supply house. Same ABC product.
