I have Racor 1000MA’s. They take Racor 2020 filter elements. These filters come in 2 micron, 10 and 30 micron. Which one is correct for my 1999 41PC with Cummins 6CTA 8.3 450 Diamonds?
Most but not all, use 20 micron filter as primary and 2 micron as final.
As we all know about diesels and the fuel, the filters can clog up fast depending on where you fill up. Can also use the 30/20 micron and a 10 last but keeping stuff out of the injectors would be key
