For 31 Years of use the filter was not too bad. This means the Racor that was in front of it did a decent job of protecting it. This is a large particulate filter so you would not expect it to be too bad being on the clean side of two other filters.


If the pump had been located on the fuel tank side of the primary filter, it would have been considerably worse.


As I mentioned, it's often the gasket that's the weak link.
