Dorman 904-921 Fuel Injector Line
Fuel Injector Line for Ram 2500 and 3500
This Dorman fuel injector line is a direct replacement for specific Ram diesel applications, built to match the original fit and routing. It is engineered for the fuel injector feed path on 2019-2023 Ram 2500 and Ram 3500 models at cylinder 1, with steel construction and OE-style thread specifications.
- Direct replacement fuel injector line for specific Ram applications
- Fits 2019-2023 Ram 2500, cylinder 1
- Fits 2019-2023 Ram 3500, cylinder 1
- Steel construction with gray/silver finish
- Female inlet and outlet fittings
- Inlet thread size: M16 x 1.5 metric fine
- Outlet thread size: M14 x 1.5 metric fine
- Maximum line pressure rating: 30000 PSI
- Length: 7.25 in; wall thickness: 0.087 in
OE-Style Fit and Construction
Dorman 904-921 is built to mirror the original fuel injector line design on the listed Ram 2500 and Ram 3500 diesel applications. The steel line uses female metric fine fittings and the correct inlet and outlet thread sizes to support proper connection at cylinder 1. This part cross-references Monroe Shocks & Struts (e.g., 68447764AA, 68479996AA) for the same application.
Common Problems This Part Can Address
- Fuel leakage at a damaged injector feed line
- Hard starting caused by a compromised fuel delivery path
- Visible corrosion or wear on the original steel line
- Improper sealing from worn or mismatched fittings
- Fuel pressure loss at the injector supply circuit
Installation Notes and Tips
Verify vehicle application by year, model, and cylinder location before installation. Confirm the inlet and outlet thread sizes match the original hardware: M16 x 1.5 at the inlet and M14 x 1.5 at the outlet. Inspect mating surfaces, line routing, and adjacent fuel system components for damage or contamination before final assembly.
Quality Assurance
Dorman manufactures this replacement line to match the fit and design of the original fuel injector line on the specified vehicles. The part number 904-921 is intended for Ram 2500 and Ram 3500 diesel applications listed above, with OE-style dimensions and pressure capacity for the injector feed circuit.
