This was installed on the White 2-135 tractor I purchased with a 5.9 Cummins. No idea how long it’s been on or how many hours. Trying to decipher the maintenance history I received it may have been on the tractor for around 2 years. Because this is the only filter I chose to reinstall a water separator instead of going back with this one. It looks like I made the right call based on the amount of water in the fuel filter. I put a Baldwin BF1226 back on.
