Of those that did have the gauge and sender assembly installed, many if not most were plagued by leaks from that area due to its construction.
The factory made the multi-part assembly out of thin gauge stamped steel that was prone to bending under the small torque applied to its fasteners thus resulting in persistent leaks & the nickname for this component the "Taco Plate" (bent into a Taco shape).

Available w/o sender or as an assembly. HERE
