Important Installation Notice:

LS Fabrication does not currently offer a hose or plumbing kit for connecting the tail light fuel filler to the fuel tank. All plumbing design, routing, and installation are the responsibility of the installer.
We recommend using 1.5” (inch and a half) stainless steel tubing combined with fuel-rated hose connectors and quality hose clamps to complete the installation.
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:
The tail light fuel filler does not provide tank venting. Proper venting must be supplied by the fuel tank itself. Aftermarket fuel tanks should be equipped with an adequate vent system to prevent slow filling, fuel splash-back, or pump shutoff issues.
