Troubleshooting & FAQ

What are the signs of a failing accelerator pump?

Common symptoms include hesitation or stumbling when you try to accelerate, poor engine performance, and potential fuel leaks around the carburetor. A visual inspection may reveal a cracked or stiff diaphragm.

How can I confirm this kit fits my specific engine?

The surest way is to match your engine's serial number to the range provided (0D283222-0G760299) and confirm your model, horsepower, and year fall within the compatibility table. Cross-referencing your existing part number with Mercury 811287 or 1395-811287 is also a reliable method.

Does this kit include all necessary gaskets for the job?

This kit is designed to repair the accelerator pump circuit specifically. While it includes the core components for that task, it may not include every gasket for a full carburetor rebuild (e.g., flange mounting gasket). Please verify the product images against your needs.

Is there a recommended replacement interval for the accelerator pump?

There is no strict interval, as lifespan depends on fuel quality, ethanol content, and usage. It is best to inspect the components during routine carburetor service and replace them if they appear hardened, cracked, or deformed.

What is the difference between an OEM and an aftermarket part?

This listing is for an aftermarket replacement, not an original equipment manufacturer (OEM) component. It is engineered to meet or exceed OEM-level specifications using comparable materials and is manufactured in an ISO 9002 facility with batch inspections for consistency.

What are your shipping speeds and costs?

We ship worldwide quickly, with a typical transit time of 5–15 days for most regions. Standard shipping is free, and expedited options will appear at checkout if they are available for your location.

What is the warranty and return policy?

Our products are covered by a 1-year warranty against manufacturing defects under normal use conditions. If you encounter an issue, please contact our support team with your order details. Returns are accepted within our standard window for items that are unused and in their original condition. See our policy page or reach out for instructions.
