I have been using the system for over 25 years.The pump never failed on it's own,was always due to debris that was passed through the rotors.Now,as per Jimi Vignogna's reccomendation I use 2 "PREFILTERS" that are in the oil lines between the pan & pump.I also run a duel oil filter setup with Moroso oil filters that have NO BYPASS.My system can filtrate 36 gph and in the event of a mechanical failure,absolutley NO debris gets pumped past the filters.
