Troubleshooting & FAQ
How do I confirm this fuel pump fits my engine?
Review the Engine & Model Compatibility table on this page. Cross-reference your engine's brand, model, horsepower, and approximate year. The most reliable method is to match the OEM part number (14360T74) from your old part or service manual.
What are common signs of a failing fuel pump?
Symptoms of a bad fuel pump include the engine failing to start, sputtering at high speeds, losing power under load, or experiencing sudden surges in speed. Poor fuel economy can also be an indicator.
Is any special maintenance required for this aftermarket pump?
No special maintenance is needed for the pump itself. However, regular replacement of your engine's fuel filters is critical to protect the new pump from debris and ensure its longevity.
Can I use ethanol-blended fuel (e.g., E10) with this pump?
This pump is designed to be compatible with standard marine gasoline, including fuels containing up to 10% ethanol (E10). However, prolonged use of ethanol blends can accelerate wear on all fuel system components; always follow your engine manufacturer's fuel recommendations.
