Leak Detection Pump: Installation

The Leak Detection Pump (LDP) is attached (bolted) to the front of the fuel tank. The LDP filter is located on the end of a hose. This hose is attached to the fuel fill tube assembly below and near the fuel fill opening. The LDP and LDP filter are replaced (serviced) as one unit.

1. Install electrical connector to LDP. Push red colored tab downward to lock connector to LDP.
2. Position LDP and LDP bracket to fuel tank mounting studs and install 2 nuts. Tighten nuts to 1 N.m (11 in. lbs.) torque.
3. Raise fuel tank to body and tighten 2 strap bolts to 61 N.m (45 ft. lbs.) torque.
4. Carefully install vapor/vacuum lines to LDP, and install hose to LDP filter. The vapor/vacuum lines and hoses must be firmly connected. Check the vapor/vacuum lines at the LDP, LDP filter and EVAP canister duty cycle purge solenoid for damage or leaks. If a leak is present, a Diagnostic Trouble Code (DTC) may be set.
