Product Description
A complete sending unit with lock ring, O-ring, and in-tank fuel filter included — everything needed in one box for the early Blazer/Suburban's 21-gallon tank.
A worn or corroded sending unit is one of the most common reasons a fuel gauge reads wrong — stuck on full, stuck on empty, or drifting somewhere in between as the resistor track wears. Matching the exact ohm range and mounting style here is what keeps the new gauge reading accurate instead of just relocating the same problem.
