Well the plastic itself isn't "delicate" per se - it's actually very thick. But it becomes delicate due to the amount of force required to get the plastic bent up enough to get over the tabs. There are 3 tabs, and it's all so tight-fitted that it's a real challenge getting them all lifted over the tabs so you can slide it apart. A couple times during the process I was pretty much just hoping something wouldn't just go "snap", and my efforts all be in vain. Again, I don't know if I could do this trailside, or even in a motel room, with just the tools I carry in my tool roll, but I suppose if I did have a spare, I would attempt it before spending the $ on a new unit, and having to wait on it to arrive. Since my original pump still did work, I suppose I'll carry it with me on trips.
