Rusty air tanks - replace now or wait?
Intuition is telling me "now", but I wanted to get some advice from those who have more experience here.
As you can see, my air tanks are fairly rusty, but seem to be mechanically sound. The only leak I seem to have right now is coming from the air dryer, which I plan to replace. I was contemplating replacing the air tanks at the same time (all 4 to the tune of $159 each). My question is, is it really worthwhile to replace them now, or do we think they're still serviceable?
Obviously I'm not asking about my specific tanks, moreso the experiences of others that have had rusty air tanks.
