By-Pass Kit for Mechanical Fuel Pump - 1 Per car

Used in conjunction with the electric fuel pump.  This kit eliminates the possibility of the electric fuel pump forcing fuel into the oil pan if the original diaphragm and seal are compromised.  Safely converts your original mechanical pump into a straight-through mode.  This is useful if the fuel side of the mechanical pump is not working but the vacuum side still works.  Or if you want to maintain the look of the original pump while using a remote electric fuel pump.

Kit contains stainless backing plate and two fuel proof Viton­® seals for the lower half of the mechanical fuel pump.
