TBI / Vortec 87-98 Truck 6AN Supply Fuel Line

The TBI / Vortec 87-98 Truck 6AN Supply Fuel Line from ICT BILLET is an essential fuel delivery component engineered for late-model Chevy and GMC truck builds running throttle-body injection or Vortec engine conversions. This fuel line bridges the gap between aftermarket fuel systems and factory-adjacent engine bay layouts on second-generation C/K trucks, making it indispensable for enthusiasts upgrading from carburetor setups or restoring aging fuel systems to modern reliability standards. The 6AN hose size balances flow capacity with compact routing through tight engine compartments typical of 1987–1998 truck platforms.

Built to ICT BILLET's exacting specifications, this TBI / Vortec 87-98 Truck 6AN Supply Fuel Line features proven crimped 6AN fittings that eliminate the guesswork of hose assembly and reduce leak risk at critical pressure points. The 6AN diameter (3/8-inch inside diameter) delivers adequate fuel volume for stock to lightly modified engines without the excessive bulk of larger-diameter lines, while the pre-cut length accommodates OEM and custom fuel pump locations common in conversion builds. Hose construction resists ethanol-blend fuels and withstands the pressure demands of electric fuel pumps (typically 5–7 PSI for carbureted systems, up to 40+ PSI for modern EFI conversions when paired with appropriate regulators).

Mechanics and engine builders restoring or converting 1987–1998 Chevy and GMC trucks will find this TBI / Vortec 87-98 Truck 6AN Supply Fuel Line simplifies fuel system plumbing on TPI, Vortec 350/305, and carbureted platform swaps. Its compact design fits tight engine bays where full-length lines would require awkward routing or custom bends, saving installation time and reducing the risk of fuel line abrasion against block or headers. Verify fuel pump type and regulator compatibility before ordering to ensure your system matches the hose's pressure rating and flow capacity.
