Greetings Bud, If the diameter of the bowl of the 'filter king' is the same as the diameter of the sediment bowl on a std AC fuel pump found on a TR4 (2 inches) NAPA part #730-9510 will work. This gasket is good quality rubber and provides a better seal than a cork gasket. Best wishes for the New Year. Jay '64 Tiumph TR4 since '67
