Can you post a picture rear seat. I have a 2000 DD and there is a screw off lid in the bottom of the ski locker. I had to remove my rear seat to get access to fuel line.

One issue was the fuel line and fuel filter get hot when you sit for awhile and create vapor lock. I found it helpful to open the dog house if I was sitting for while. I have since installed a heat shield around the gas filter which has helped a lot.
