Access to Fuel Tank from inside?

Does any one if workhouse put in a access to top of the Fuel Tank and about where it would be?

The issue I have is the flare nut to the Fuel Filter is frozen. After lot of work I did manage to free up the other two flare nuts but the one on the input side won't budge. The gas line wants to twist to much because of hoe it's routed.

If I break it then I would have to replace the line and still have the same problem of having access.

Thanks Tim McHugh

Welcome Tim to the Newmar forum & irv2.
As far as I know Newmar has never placed a access hole under bed area or in floor for that matter to get to top of your gas tank.
You will need to drop tank to change fuel pump or a filter inside.
The fuel line filter is on your chassis rail.
Here is a thread where someone with a Ford cut a hole to access top of tank.

Access to the top of Gas Tank

Thanks for your response, I might have to change the the gas line going from the tank to the input of the Filter. there are 3 lines for the fuel system. I like your input on cutting a hole on the floor in the bedroom. I currently have a full tank of gas. All this because of a rusty fitting on the gas line.

I'm looking at the options availale depending on what happens.

Thanks again;

Can you move the filter away from the frame far enough , so that you could hold the nut and spin the filter ?? Or is it the nut rusted into the fuel filter fitting, if the nut moves at all in the filter, and the nut twists the line when turning, then spinning the filter may work. Had similar issues on a Dakota P/u.

I have replaced my fuel filter with OEMY's product, and understand the problem. On my chassis, a W22, there would be room to cut the fuel line, and install a flare fitting, if you do not have enough slack in the line to go to the fuel filter, you could then splice in a intermediate piece. I personally would do that before dropping the tank. Dropping the fuel tank is a big project, been there and done it on another motorhome. If you decide to cut through, it would probably be through the basement passthrough, not the bedroom. Working headroom would be tight, but I have thought about that if I ever need to replace the fuel pump.
