304c cr hydraulic hose bucket

I've blown a hose from the bucket to the cab on a cat 304c cr. The hose goes under the cab and I think ends up at the valve stack at the back. I took it off at the steel line on top of the boom but it doesn't want to budge when I attempt to pull it through to the back. Is it fastened under the cab or attached to another stack? I took the floor deck off and couldn't see a thing. Is there a website that shows the hose and I could order one and see how long it is? The dealer said it's 41 inches long and I'm measuring close to 54 inches going into the front of the cab. thanks
