Detailed Description

Standard Ignition LDP01 is engineered as an OE replacement leak detection pump for the evaporative emissions system. Its diaphragm and spring are calibrated to open and close with the correct response, helping the switch report accurate voltage readings during EVAP testing. The connector and terminals are built to match OE fitment, supporting solid conductivity to the engine wiring harness. This part cross-references Dorman OE Solutions 310-207 for the same application.

For drivers searching for a Dodge Ram 1500 EVAP leak detection pump, Chrysler Voyager evaporative emissions pump, or Jeep Liberty leak detection pump replacement, the LDP01 provides a direct-fit service part for the listed applications. The part number LDP01 is also a useful reference when matching the correct evaporative emissions system leak detection pump for Chrysler, Dodge, Jeep, and Plymouth vehicles.

Common Issues This Part Addresses

• EVAP leak detection faults stored by the engine control system
• Failed or inconsistent evaporative emissions pressure or vacuum testing
• Damaged electrical connection at the pump connector or terminals
• Cracked, heat-damaged, or worn pump housing
• Incorrect switch response caused by diaphragm or spring wear

Installation Notes and Tips

Verify hose routing, connector style, and hose sizes before installation. Inspect the EVAP hoses and wiring harness for cracks, corrosion, or heat damage so the replacement pump can operate with a clean vacuum path and stable electrical connection. Confirm the vehicle application against the listed fitment before ordering.
