WPLLD Site Prep and Installation Guide
Red Jacket Pumps (Except Quantum and The Red Jacket)
4-5
Remove the capacitor cover from the pump head and place the protective plastic cap (removed from the WPLLD
transducer) over its threads. Put the cover aside for now.
Also, some older Red Jacket pumps may have oval-style capacitors which are too tall for WPLLD transducer installa-
tions. An oval capacitor should be replaced with Red Jacket nos. 111-661-5 (1
-1/2
HP pumps) or 111-092-5 (1/3 or
3/4 HP pumps).
IMPORTANT! If fuel is present in the STP’s capacitor well, you must identify and correct the source of the
leak before proceeding.
4. Cut the black wire (originating from the 240 Vac power source) in the capacitor housing (see Figure 4-5). Using the
electrical connector provided, connect the 2 cut black leads to either one of the wires on the WPLLD transducer.
5. Cut the yellow or orange wire (Figure 4-5) in the capacitor housing. Using the electrical connector provided, connect
the two cut yellow or orange leads to one of the wires in the WPLLD transducer.

6. Place the shield (from the installation kit) into the capacitor housing with open side up. Hold the shield at an angle
and place notched tab into the compartment first. Guide the two wires from the WPLLD transducer into the notch on
the shield [Figure 4-6], leaving as much slack in the wires as possible above the shield (this will prevent stressing
them when the transducer is threaded into the pump).
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.
