Does anyone know how to remove this hose, I’ve pulled the clamp off however if I pull on it, it won’t move. I have a replacement for it and it dosnt seem like it would go far back past the firewall

 

If you don't have a hose pick, take a utility knife, and cut it off slicing length wise. No need to dig the blade deep into the metal pipe. Just be easy with it. Done it many times.

 

A heat gun will relax the rubber and make it easier to get off. A hair dryer might work. You don't want to set anything on fire. If you want to save the hose (doesn't sound like you care), put your hand on the hose while heating it. If it's too hot for your hand it's probably too hot for the rubber.
