Specs At A Glance

Good To Know

Q: How many injectors does this engine use? A: The 1503 engine runs one injector per cylinder, so check the full set and replace any that test out of spec. Order the quantity you need based on your service plan.

Q: Do I need to replace the seals when installing this injector? A: Replacing the O-rings or seals during installation is good practice, since old seals can leak or allow air into the fuel charge. Confirm the correct seal part for your machine before you begin.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
