Product Details

The Keystone GM3900118 is a factory-style OE replacement fuel tank designed for the Buick Regal coupe. Built from steel construction, this direct-fit tank restores your vehicle's fuel system to original capacity and function without modification.

Key Features:

  • 17-gallon capacity — matches original OEM fuel volume
  • Steel construction — durable, OE-style material for long-term reliability
  • Includes integrated filler neck — complete assembly for straightforward installation
  • Coupe fitment — designed specifically for 2-door body style
  • Factory-style OE replacement — engineered to match original specifications for a direct drop-in fit
  • OEM cross-reference: 559451 (Hollander: 559451)

This replacement tank is ideal for restoring a leaking, rusted, or damaged original unit. The steel construction and OE-matched dimensions ensure proper fitment and compatibility with existing fuel sending units and mounting hardware.
