- Disconnect the electrical connector carefully and remove the original injector according to the engine manufacturer's procedure.
- Inspect the injector seat, fuel rail, connector, and sealing surfaces. Replace damaged seals with the correct seals for the engine.
- Install the new injector without twisting or damaging the seals, then reinstall the fuel rail using the manufacturer's specified procedure and torque values.

Troubleshooting & FAQ
Is this injector new or remanufactured?
This listing is for one 100% new fuel injector. It is not a used or remanufactured injector.
How do I know whether this injector fits my engine?
Match the complete engine family, model, stroke, displacement, and serial-number condition shown above. Also compare the original injector and electrical connector before ordering. If the engine identification or original part differs, do not assume compatibility from horsepower alone.
Does this listing include four injectors?
No. This product is sold as one individual injector. A set of four requires four units purchased separately.
Does the package include a seal kit?
No seal kit is specified as included. Use the correct replacement seals for your exact engine if the existing seals are damaged or are not reusable.
Is this an OEM Mercury or MerCruiser injector?
No. This is an aftermarket replacement part. Mercury and MerCruiser part numbers are shown only as reference numbers for application identification.
What symptoms can indicate a faulty injector?
Possible symptoms include rough idle, misfire, hard starting, poor acceleration, uneven engine operation, or increased fuel consumption. These symptoms can also be caused by other fuel, ignition, electrical, or mechanical problems, so diagnosis should be completed before replacement.
Can I clean the original injector instead of replacing it?
Professional injector testing and cleaning may help with some deposits, but cleaning will not correct every electrical, mechanical, or leakage failure. Test the original injector and follow the engine manufacturer's service recommendations.
What are the shipping and warranty terms?
Shipping options and delivery estimates are shown at checkout. Warranty and return eligibility are governed by the current store policy and the order terms applicable to the purchase.
Safety & Important Information
- Fuel-system work can present fire, pressure, and chemical hazards. Follow the engine manufacturer's service procedure.
