Product Details

The Replacement REPF314578 is a complete in-tank electric fuel pump assembly engineered as a direct OEM replacement for 1998–2000 Ford Crown Victoria, Mercury Grand Marquis, and Lincoln Town Car models equipped with the 4.6L V8 engine. This assembly replaces Ford OEM part number XW1Z9H307AG and is designed to restore factory-level fuel delivery performance without modification.

Key Features:

  • Complete fuel pump module assembly — ready for direct installation
  • Replaces Ford OEM part number XW1Z9H307AG
  • Designed for 8-cylinder 4.6L engine applications
  • Includes fuel pump, sending unit, and mounting hardware for a complete repair
  • Engineered to meet original equipment specifications for fuel pressure and flow rate
  • Restores proper fuel delivery to eliminate hard starts, stalling, and power loss

A failing fuel pump assembly can cause symptoms such as difficulty starting, engine hesitation, rough idle, or stalling under load. Replacing the entire assembly — rather than just the pump motor — ensures all wear components are refreshed simultaneously, reducing the likelihood of repeat failures. This unit is built to deliver reliable, long-term fuel system performance.

All went well

You had what I needed so I ordered it

Good experience!

Came quick!

Shipping took longer than expected as I paid for expedited shipping. I reached out to ask why it wasn't sent two day and got no reply. The customer service could really use improvement and this is reflected in multiple reviews. However, the products arrived safely and as described. I'm very satisfied with the pricing as well. At the end of the day, that's the most important thing.

Very good, Item was as expected

My order processed quickly and was shipped and received quickly. Perfect deal.
