I just replaced mine along with a new hose. I would have a replacement in hand even if you don't want to replace it. There is a o-ring seal that would be good to replace if you pull the strainer out. I think it is a lot of trouble to drain the tank so for $ 25 it is not worth it to me to try and reuse parts like that. If you screw up the strainer taking it out or find it damaged, you might not be able to drive it until you get a new one.
