Bob....without seeing photos of your coach, I'll give you the info I used for adjusting the gauge on my 2005 Diplomat.
The tank runs side to side, between the two fuel doors (driver and passenger). Typically, the panel that contains the fuel door, on both sides, is not a regular bay door, but it does open. You should be able to see hinges along the top edge. If you look under the panel, there are two tabs, screwed down to the body. Remove the screws and the panel will lift up. You'll need a broom handle to hold it open.
On the driver's side, when you open that panel, or you may even have a bay door, you'll find the fuel sending unit on the top of the tank, about 18 inches in from the edge of the coach. It's a Centroid as described above. It's adjustable, but you'll probably have to clean the undercoating spray off of the screws. On my 2005 Diplomat, I initially adjusted it to read the way I wanted it to.....needle more to the right when full. A few years later the sender quit. I adjusted it again and it worked until I sold the coach after10 years of ownership.
So....try and adjust it first, before replacing it. Again, the link provided in the post above, has adjustment instructions as you arrow through the website.
