Hidden Tail Light Fuel Filler Kit – 88-98 GMC Chevy OBS Truck

Clean, hidden, and functional — this is the ultimate gas filler relocation upgrade for your 1988-1998 Chevy or GMC OBS truck. Designed using 3D scanning and CAD precision, this kit hides your fuel filler neatly behind the taillight for a smooth, custom look.

This product does not fit the Suburban, Tahoe, or Stepside.

Note: these taillights have only been tested with stock taillights and the United Pacific lights included in this listing. Please confirm it will work with your setup before purchasing.

Features:

• ✅ Includes a stainless steel fuel filler neck
• ✅ Precision-fit CNC laser-cut steel construction
• ✅ Works with OEM taillights only
• ✅ Grab latch secures when closed
• ✅ Instructional video available for easy install

Note:

• May not fit fuel nozzles with vapor-seal systems (e.g. California pumps).
• Does not fit the Suburban, Tahoe, or Stepside.

Important Installation Notice:

LS Fabrication doesn't currently offer a hose or plumbing kit for connecting the fuel filler to the tank — all plumbing design, routing, and installation are the installer's responsibility. We recommend 1.5" stainless steel tubing with fuel-rated hose connectors and quality hose clamps.

For best performance and fueling behavior:

• Keep the plumbing as straight as possible
• Minimize bends and turns
• Maintain maximum downward slope from the filler neck to the fuel tank

Venting Notice: this kit doesn't provide tank venting. Your fuel tank needs its own adequate vent system to prevent slow filling, splash-back, or pump shutoff issues.
