To get to the tabs that say "PULL HERE", I had to disassemble the spool - the center portion around which the hose is wrapped around. On mine, the spool is essentially an assembly of 2 half-cylinders of plastic.
1. There are 4 screwdriver pry-slots - 2 on each side/seam were the half-cylinders meet. Stick a screwdriver in these slots and give it a gentle twist.
2. You'll note 4 locking tabs - 2 per half-cylinder - on the inside near the ends that will come loose as a result.
3. These half-cylinders then have to be pulled apart as they also have a pair of mating sleeves/posts.
Once I pulled the spool apart, I was able to get at the 2 "PULL HERE" tabs near the out-tube to remove the in-tube.
