Hey! Welcome to Just Answer. My name is JacobTD; I will help you figure this out.
I am an Expert in this Category, and picked your question because I have firsthand
knowledge on this particular vehicle. So let’s get started.
This is a low pressure feed line. SO you can do what ever it take to get off. You can even cut line as for it is not high pressure. It should be able to after removing hose clamp if having one. twist and pop off.

I already have the pump/reservoir off the vehicle but can't get them to separate, so I can replace the pump only.
