you still have a really great filter there! but please fill that tank up asap so you dont burn up the motor. because a new motor for that thing is going to run you at least 150. Do you mind if I ask how you got it and how old it is. Because both the 2260 and the 2250 are discontinued I belie. I picked up my 2260 used and looked on the motor and it says it was made in west Germany. Which means my filter is 20 years old because there hasnt been a such thing as a west germany since the berlin wall fell in 1989.
