WPLLD Site Prep and Installation Guide

5. Remove the O-ring from the installation kit and lubricate it lightly with mineral oil or other suitable lubricant. Install
the O-ring onto WPLLD transducer by carefully pushing it over the external threads and into the groove above the
threads. Remove the protective plastic cap from the WPLLD transducer (do not discard cap).
6. Remove the capacitor cover from the pump head and place the protective plastic cap (removed from the WPLLD
transducer) over its threads. The capacitor cover must remain with the pump because it contains important safety and
manufacturers information. Snap the capacitor cover in the bracket.
IMPORTANT! If fuel is present in the STP’s capacitor well, you must identify and correct the source of the
leak before proceeding.
7. Cut the black wire (originating from the 240 Vac power source) in the capacitor housing (see Figure 4-13). Using the
electrical connector provided, connect the 2 cut black leads to either one of the wires from the WPLLD transducer.

8. Cut the orange wire in the capacitor housing. Using the electrical connector provided, connect the two cut orange
leads to the other wire from the WPLLD transducer.
WARNING
DO NOT APPLY ANY THREAD SEALANT OR PIPE DOPE TO THE THREADS OF THE
WPLLD TRANSDUCER OR TO THE THREADS OF THE STP’S MOTOR CAPACITOR WELL
INTO WHICH IT IS SCREWED.
The metal-to-metal joint created by threads of the WPLLD transducer in the STP’s capacitor
well ensures a restricted flame path to prevent propagation of a spark or flame to a hazard-
ous area. If any thread sealant or pipe dope is applied to the threads of the WPLLD transduc-
er or to the threads of the capacitor well, the flame path may not be restricted, potentially
resulting in serious injury or death from explosion.
