Yes, from above. It was a pain to get to, up against the back firewall, to get that clamp off. Even with the right tool. And then it was a pain to pull the old tube off. Pulling off the rear took quite a bit of force, which is hard to do, since you can't get a good grip, and at a good angle, on the tube. The front, I feared breaking the section of tube off the engine, so after tugging on it for a while, I just used a razor and carefully cut a slit in it in order to pull it off.
