As the title reads this is what I'm doing. From what I have read it looks to be an easy job. Are there any "gotcha's" that you can think of?

I milked this thing out for a while, until i was 95 miles away from home last weekend and it completely went out. Made it back to the driveway though.

 

I could have typed the exact same lines a few years back! I can't remember if there was anything special that needed to be done to replace the "unit". I just recall that it was weird to not have to bleed the thing. Just swap the new stuff in and go.
