I’m replacing the fuel system on my 4/1976 South American 40 from tank all the way to carb. While investigating the benefits of the fuel return, I’ve decided to add one.
I’m making all 5/16 fuel lines. In looking at my aftermarket h3662 carb, (replica of 21100-61012) It appears there is a bolt blocking fuel return ( see image #1) . What’s strange about the H3662, all I’ve seen online do not have fuel return line at the carb. Has anyone seen an h3662 with fuel return banjo bolt similar to image #2 below? Anyone know where I can buy one?

NOTE re: fuel return. (from Fj40jim)
There is a return system. It consists of a banjo bolt and a banjo fitting. The banjo bolt contains a brass restrictor (jet), and behind that is a rubber check valve/pressure regulator. The restrictor limits maximum fuel return flow. The rubber check valve has a cracking pressure, to maintain a minimum pressure in the fuel inlet of the carb.
The banjo bolt is 12x1.25 with crushwashers, the banjo fitting is 13x1.5 compression.
