Standard Ignition LDP14 Evaporative Emissions System Leak Detection Pump

OE-Style EVAP Leak Detection Pump

The Standard Ignition LDP14 is a direct-fit evaporative emissions system leak detection pump for vehicles equipped with an EVAP System Integrity Module (ESIM). It uses engine vacuum to help verify evaporative leak integrity, with a calibrated diaphragm and spring that support accurate switch voltage readings.

Built for Chrysler, Dodge, Jeep, and Ram applications, the LDP14 is a practical replacement for common EVAP fault concerns on models such as the Chrysler 300, Dodge Charger, and Jeep Wrangler.

Key Features

• Direct-fit OE replacement for EVAP leak detection service
• Precision-calibrated diaphragm and spring for accurate switch response
• Uses engine vacuum to detect evaporative system leaks
• High-temperature OE-style plastic housing for fit and durability
• OE-quality connector and terminals for solid harness connection
• Female connector design with blade-style male terminals

Detailed Description

Standard Ignition LDP14 is engineered as an OE replacement evaporative emissions system leak detection pump for Chrysler, Dodge, Jeep, and Ram vehicles using an ESIM setup. The unit is built around a calibrated diaphragm and spring assembly that opens and closes with controlled response, helping the system produce accurate voltage feedback to the switch. Its high-temperature plastic housing supports proper fitment in demanding underbody conditions, while the OE-style connector and terminals help maintain reliable conductivity to the engine wiring harness. This part number, LDP14, is a direct replacement choice for service work on applications including the Chrysler 300, Dodge Charger, and Jeep Wrangler.

This part cross-references Dorman OE Solutions 310-215 for the same application.

What It Helps Address

• EVAP leak detection faults
• Check engine lights related to evaporative emissions monitoring
• Improper switch voltage readings in the ESIM system
• Vacuum-related leak detection issues
• Connector or terminal fitment problems at the harness interface

Installation Notes and Tips

Verify the vehicle uses an EVAP System Integrity Module (ESIM) before ordering. Confirm connector style, terminal layout, and hose connection match the original unit. On fitment-specific vehicles such as the Chrysler 300, Dodge Charger, and Jeep Wrangler, compare the original pump location and housing shape to the replacement before installation. Clear diagnostic trouble codes after repair and recheck the EVAP system for proper operation.

Quality Assurance

Standard Ignition builds this replacement with OE-style housing, connector, and terminal design to support accurate fit and electrical connection. The LDP14 is intended to restore factory-style evaporative leak detection performance on listed Chrysler, Dodge, Jeep, and Ram applications.
