Standard Ignition GDL401 Fuel Feed Line

OE Fuel Feed Line for GDI Systems

Standard Ignition GDL401 is an OE replacement fuel feed line for direct gas injection applications. It is built as a metal high-pressure line with screw-on fittings at both ends, sized 14mm x 1.50, for a direct connection between the pump and fuel rail.

Compatible with Hyundai Elantra, Sonata, Santa Fe Sport, Tucson, Elantra GT, and Kia Optima, Sportage, Sorento, Forte, Forte Koup, and Forte5 applications that use a high-pressure fuel feed line from pump to fuel rail. The Standard Ignition GDL401 is made for gas fuel delivery systems with GDI and direct system requirements.

Application Details

Standard Ignition GDL401 is used in Hyundai and Kia vehicles with GDI fuel systems where the high-pressure line runs from the pump to the fuel rail. This part cross-references Dorman OE Solutions 904-975 for the same application. If you are replacing a worn or leaking fuel feed line on a Hyundai Elantra or Kia Optima, GDL401 provides the correct OE-style connection points and dimensions for the listed vehicles.

What This Part Helps Address

• Fuel seepage at the high-pressure line connection
• Cracked, corroded, or damaged metal fuel feed tubing
• Improper sealing at the pump or fuel rail end
• Fuel pressure loss in direct injection systems
• Service replacement for a failed OE fuel line

Installation Notes

Verify thread size, fitting style, and vehicle application before installation. This line uses screw-on 14mm x 1.50 fittings at both ends and is intended for direct fuel system routing between the pump and fuel rail. Clean the mating surfaces and inspect the fuel rail and pump ports for wear or damage before assembly.

Quality Assurance

Standard Ignition supplies OE replacement components for fuel system service, and GDL401 is built to match the listed direct-injection applications and connection specifications.
