New 74 Sending Unit - help with extra pipe? Jul 10, 2020 15:16:58 GMT -5

My sending unit on my '74 isn't exactly like my original stock one, there is an extra pipe besides the fuel pipe and electrical contact.

Does anyone know what that extra pipe, which looks like a breather, does and what should I do with it? I already have a vent on the very top of the tank.

Here's a pic of it:

I appreciate the help.

That style sender must be shared with some fuel-injected application. Cap it off and hit the road
