Dorman 904-965 is a direct-fit intermediate front fuel injector line built to replace the original line on select Cadillac, Chevrolet and GMC models for a secure, pressure-rated fuel connection.

This replacement fuel injector line is engineered to match the original geometry and mounting points, and it arrives with vehicle-specific hardware so you have what you need for a proper installation. Designed and tested to withstand the pressures typical of modern fuel systems, the Dorman 904-965 provides a cost-effective alternative to expensive dealer components while maintaining fit and function. Before ordering, use your vehicle’s make, model and trim in the garage tool to confirm compatibility with your year and model.

Will this fuel injector line fit my vehicle?

The 904-965 is built to match factory specifications for a range of Cadillac, Chevrolet and GMC applications across multiple model years. Fitment depends on year, model and trim, so checking the garage tool ensures you select the correct part for your vehicle. If your vehicle appears in the compatible list, this line is intended to bolt into the same mounting points as the original.

• Compatible with many Escalade, Suburban, Tahoe, Silverado, Sierra, Corvette, Camaro, Express and Savana models (see product compatibility list).
• Includes vehicle-specific mounting hardware in the box for complete replacement.
• Confirm by entering make, model and trim into the fitment checker before purchase.

How is this line engineered to handle engine conditions?

Dorman manufactures this injector line with a material-hardening process and quality checks focused on pressure durability and long-term reliability. It is intended to tolerate the high-pressure environment of fuel injection systems and to keep fittings sealed under repeated thermal cycles. The construction mirrors original contours to avoid strain or misalignment.

• Material-hardening process for enhanced pressure resistance.
• Precision-formed ends and bends to match OEM routing and clearances.
• Quality-tested to reduce leaks and premature failure compared to worn OEM lines.

Do I need to replace the entire injector line or just a section?

Fuel injector lines use crush-style sealing at the fittings, which are single-use once compressed. When a seal or fitting is disturbed during service, replacing the entire line assembly ensures a fresh, reliable seal and prevents fuel leakage. This part is offered as a complete replacement to simplify service and restore factory-fit sealing integrity.

• Crush-style seals are one-time-use; replacement prevents leaks after service.
• Complete line replacement avoids mismatched fittings and alignment issues.
• Supplied mounting hardware helps ensure proper torque and seating of fittings.

What are the benefits of choosing this Dorman replacement over dealer parts?

The Dorman 904-965 delivers OEM-style fit with a lower price than many dealer-sourced components, while including the necessary installation hardware. The part is tested to meet functional expectations and offers an economical route to restore proper fuel line performance without compromising routing or attachment points.

• Cost-effective compared with dealer-sourced replacements.
• Includes vehicle-specific mounting hardware for a full install.
• Quality-tested to provide dependable service in specified applications.

Who this is for: The Dorman 904-965 intermediate front fuel injector line is intended for owners, mechanics and fleet technicians servicing compatible Cadillac, Chevrolet and GMC vehicles who need a reliable, direct-fit replacement. It's appropriate for routine maintenance, repair after a leak or when replacing fuel system components where crush-style seals must be renewed. If you want an aftermarket part that restores factory routing and includes installation hardware while saving cost over dealership parts, this Dorman line is designed for that purpose.
