If your classic GM car's fuel gauge is inaccurate or the tank isn't feeding fuel properly, this sending unit could be the fix. It's designed for 1977-1985 Buick LeSabre/Riviera, 1981-1985 Chevrolet Impala/Caprice, 1977-1985 Oldsmobile Delta 88/Toronado, and 1977-1981 Pontiac Bonneville/Catalina, among others — basically the rear-wheel-drive B-body and similar models. It has two outlets (no vapor return line) and fits a 24-gallon tank on many applications. The unit includes the float, arm, and sensor that tell your gauge how much fuel is left, but note: it does NOT include a fuel pump — it's just the sending unit. It matches OEM numbers like 692-051, 25000599, and FG10B. Installation requires dropping the fuel tank, so it's a bit of a job, but it's straightforward if you're comfortable with basic mechanics. A quality aftermarket replacement that restores reliable fuel level readings and proper fuel delivery for your vintage cruiser.
