The Carter SX-9646 mechanical fuel pump is a popular choice among car enthusiasts for its reliability and durability, especially for older Mercury Montegos with 5.0L and 5.8L V8 engines. Here are some pros and cons to consider before purchasing this fuel pump:

3. High flow rate: The Carter SX-9646 has a higher flow rate than the original equipment fuel pump, which can improve engine performance and fuel economy.

4. Durable construction: The fuel pump housing is made of cast iron, which is more durable than the plastic housing found in some aftermarket pumps.

5. Availability: The Carter SX-9646 is widely available from various automotive parts retailers, both online and in-store.

1. Cost: The Carter SX-9646 fuel pump is more expensive than some aftermarket electric fuel pumps. However, the higher cost may be justified by its reliability and durability.

2. Size: The Carter SX-9646 is slightly larger than the original equipment fuel pump, which may require some modifications to fit in tight engine bays.

3. Noise: Some users have reported that the mechanical fuel pump produces more noise than an electric pump. However, this is generally not a significant issue.

In conclusion, the Carter SX-9646 mechanical fuel pump is a solid choice for Mercury Montego owners looking for a reliable and durable replacement fuel pump. Its high flow rate can also provide performance benefits. While it may be more expensive than some alternatives, the peace of mind that comes with a mechanical fuel pump is worth the investment for many enthusiasts.
