If a check valve is necessary, purchase 20-1534 (separately) to replace the fitting(s) under the fuel hat. ELECTRICAL The custom designed stainless steel electrical studs easily handle the high current demand that compact multi-pin bulkhead connectors lack. They have an anti-rotation feature that prevents the terminals from spinning. These serviceable connections are hermetically sealed and impervious to all standard and exotic fuels. Non-conductive anodized aluminum acorn nuts are provided to prevent any accidental short circuiting. Furthermore, the in-tank wiring is insulated with high quality chemically resistant ETFE.  NOTES Single pump installations can re-use the OEM fuel pump wiring. It is recommended to upgrade OEM wiring to ensure the single pump is receiving full power and operating at maximum potential. If using a second pump, a new dedicated relay and fuse pump MUST be used.
