Well, I've decided to forge ahead with fuel filling behind the panel van tail light (my panel beater called me pig headed) and just thought to update this thread. I've mapped out a plan for where to run the fuel line using 50mm PVC piping and should be able to get this bent up without too much trouble.

I'm also currently doing a prototype LED version of the RHS tail light that should do away with the entire light body so only the lens is left with a flat sealed metal plate as a backing. This should hinge nicely.

Will update further as it comes along. Cheers
