Yes the trunk floor on mine was contacting the top of the sender.
I made an access panel out .063" 2024 T3 alum. The access panel does not touch the sender as it sits above the floor. Although I primed and painted it
I still attached a section of Velcro fuzzy self stick to the bottom in case it ever had a load in the trunk.
If you have the tube type sender its a VDO PN 224-221 (8.3") approx $33.00.
Ordered mine thru.
