Detailed Description

Sparta PN4084 is built for higher-mileage and earlier-model vehicles and is distributed through Delphi, an OE fuel system supplier. This fuel pump hanger assembly is engineered as a direct replacement for the original in-tank fuel delivery module on select Buick LeSabre, Oldsmobile 88, Oldsmobile LSS, and Pontiac Bonneville models from 1997 through 1999. The assembly includes the pump, sending unit, external strainer, seal, and lock ring to restore fuel delivery and fuel level signal performance in one service part.

This part cross-references Carter P77379H for the same application.

What It Helps Fix

  • Hard starting caused by weak or failing in-tank fuel pump output
  • Engine stalling from inconsistent fuel pressure
  • Incorrect or erratic fuel gauge readings from a worn sending unit
  • Fuel starvation under load from restricted pump performance
  • Fuel delivery issues related to a damaged hanger assembly or degraded seal
