Product Details

Standard Ignition GDL513 is a direct fuel feed line built for high-pressure fuel delivery between the pump and fuel rail. Its OE replacement design supports factory-style fitment on Lexus GS350, RX350, and RX450h applications, as well as Toyota Camry, Highlander, Sienna, and Tacoma models listed for 2016-2018 coverage. The screw-on 14mm x 1.50 fittings and molded metal construction match the requirements of direct injection service where secure sealing and accurate routing are critical. This part cross-references 2-34454 and 800-6555 for the same application.

Common Problems This Part Can Address

• Fuel seepage at the high-pressure line connection
• Cracked, corroded, or damaged fuel feed tubing
• Poor sealing at the pump-to-rail fuel path
• Incorrect routing after prior fuel system repair
• Loss of fuel pressure caused by a compromised line

Installation Notes and Tips

Verify the vehicle’s direct injection fuel system layout before installation and compare the existing line length, thread size, and fitting style to the GDL513. Clean the connection points thoroughly, inspect the pump and rail ports for damage, and tighten the screw-on fittings to the manufacturer’s service specifications. Because this is a high-pressure fuel component, confirm there are no leaks after installation and before returning the vehicle to service.

Quality Assurance

Standard Ignition supplies OE-style replacement components for fuel system repair, and the GDL513 is built to match the listed application requirements for direct injection service.
