Some of the Renault Fluency covers the manhole covers the body of approximately 0.5-1cm. It may be that the cap of the gas tank itself is removed (held on the brackets). In this case, you can try neatly put it in place (it is better to preclean it).
Sometimes it's like the decorative cover of the hatch is "falling off." In fact, it is very easy to install, but it stops. Therefore, it is recommended to be glued to superglue.
It also happens that the cover is above the body level because the curve is set at the plant. If this is the case, then you need to contact the dealer who needs to correct the problem.
