The Problem: When the injector tube wears down, it can lead to fuel leakage, which can cause the vehicle to hard start or not start at all.

Our Response: TechSmart’s Diesel Injector Tube is a new technology designed to get 2003-07 Dodge Ram 5.9L trucks running smoothly again. The part covers more than 585,000 VIO.

TechSmart Tip: Two things to keep in mind: 1) replace the injector tube each time you replace the fuel injector and 2) torque the connector tube nut down to 37 ft-lbs.
