Fuel Injection Tools

Modern diesel injectors live at extreme pressures and tolerances — servicing them with pry bars is how $500 jobs become $5,000 ones. David’s Heavy Duty Tool Sales stocks fuel injector tools for heavy-duty diesel work: injector pullers, cleaning equipment, seat cutters and the specialty tooling that protects components on the way in and out.

Injector Removal & Installation

Seized injectors need controlled extraction. Our injector pullers and slide-hammer adapters remove stuck injectors without damaging bores, while installation tooling seats new units squarely with the proper protrusion.

Injector Cleaning & Seat Service

Carbon on an injector seat causes compression leaks and hard starts. We carry injector seat cutters, bore brushes and cleaning kits that restore sealing surfaces to spec — the difference between a lasting repair and a comeback.

Diagnose Before You Pull

Confirm the cylinder before surgery: pair this tooling with compression test adapters from our engine tools line and diagnostics equipment to verify which injector is actually the problem.
