NS.
It’s hard to say. This was probably removed, dropped in the open sump, and then pulled out at a later date. That sump will have crankcase oil, boron coolant, governor oil, etc. It’s likely it was fouled primarily in that manner—rolling around in an oily soup for a year or two. Or it could have been changed at an outlying point by a shop truck specifically because the fuel tank on that particular engine took on too much water and fouled the whole system.
Great work. Did same filter go on? Maybe I missed that. I Thank You sir
I believe so. I was merely working the switcher at that location. I didn't perform the filter service. They always have these same filters whenever I have to inspect my engine lockers.
