I have a 1975 20HP Thunderbolt with a bayonet (male end) fitting sticking out of the motor.

I went to Bass Pro before seeing the motor and bought a fuel line with the same style fitting that is supposed to connect to the motor. when I bought the fuel line it just stated that it was for Mercury motors (didn't specify year).

Is there a different style connector for these older motors or can I convert it to this different style?

Thank you in advance for any help anyone could give on this.

That a good reason for a trip to a Mercury dealer.
