Hey Jim,
If you are talking about the metal flange that you put the nozzle at the gas station into, then I believe they are the same for the same years. I know that the gas cap from my '85 is not the same as on my '82. I don't think that the lengths are any different.
Hey Matt,
I just went through this myself. My filler hose had a small crack, so I thought I would replace it while I had my tub off. I ordered the CJ8 filler hose from 4WD Hardware. Their hose was about 4"s too short. I called and spoke with one of their tech advisors, and they told me I had the correct hose. Well, their correct hose is 4"s shorter than my factory hose and there is no way it will work. I tried purchasing some filler hose from a local autoparts chain, but it ended up being coolant hose. I decided my small crack wasn't too bad and re-used my old hose. I figure I will replace it when I have to.
Anyway this might help you out. Try buying the proper sized fuel filler hose from a boat supply/parts yard. They sell many different I.D. fuel hoses, and should have one that works. Then go to Home Depot, or an electrical supply house. Purchase some flexible plastic conduit(sometimes called Raintite) that has the same I.D. as the O.D. of the fuel hose. Slip the conduit over the fuel filler hose and install on your Scrambler. The conduit is rigid enough that it will not kink, but flexible enough to fit through the holes in the tub. By placing the filler hose inside the conduit it will not kink. Hope this helps. I am not sure how economical this solution is, but i will probably try it when my hose fails.
Later,
