Under Bed gas filler neck relocation????

[romes20]

Hi, just wondering if anyone could help me out. I just purchased a 67 c10 and the previous owner put the 21 gallon tank underneath the bed. Except he made an area in the bed to lift up and left the filler hose uncapped flopping around.

Im about to redo the entire wood floor and want to relocate the filler neck in a proper location with the right cap and finish it out properly.

Just wondering what everyone did and filler neck relocation and gas cap they used. Pictures would be great.

Thanks in advance.
