Are we saying that low oil pressure from the LPOP causes the HPOP to fail?
Does abnormally low pressure from the LPOP starve the HPOP and cause rapid wear and tear, thus creating brass contamination that is observed in the oil?
If so, what is the lowest acceptable LPOP pressure? Mine never drops below maybe 25 psi at idle when its hot, and tops 50 psi at normal operating speeds.

Do you have a separate gauge and if so, where did you install the sending unit?
