Detailed Description

Standard Ignition LDP71 is engineered as an OE replacement evaporative emissions system leak detection pump for 2011-2014 Ford Fiesta models. It is designed to work with the vehicle’s evaporative emissions monitoring strategy by using engine vacuum and a calibrated diaphragm-and-spring design to help provide accurate electrical feedback to the switch. The high-temperature plastic housing is shaped for OE-style fitment, while the connector and blade terminals are built to match the factory harness interface. This part number LDP71 is a focused solution for Ford Fiesta EVAP service where correct electrical connection and consistent leak detection performance matter.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• EVAP leak detection faults
• Check engine light concerns related to evaporative emissions monitoring
• Improper switch voltage readings from a worn leak detection pump
• Poor electrical contact at the pump connector or terminals
• Fitment issues caused by a damaged or incorrect OE-style replacement part

Installation Notes and Tips

Verify the vehicle application before installation: Fits 2011-2014 Ford Fiesta. Match the female connector, 3 blade terminals, and hose connection layout to the original unit before swapping the part. Inspect the EVAP hoses, wiring harness, and connector terminals for wear or corrosion so the replacement pump can operate correctly after installation.

Quality Assurance

Standard Ignition builds this leak detection pump as an OE-style replacement with calibrated internal components, a high-temperature housing, and connector/terminal dimensions intended to match factory requirements for the Ford Fiesta EVAP system.
