69 fuel tank sending unit question

I bought a new gas tank and sending unit.my original sending has 2 lines,one 3/8 line (supply) and one 5/16 line (vent).when I got my new sending unit,it has only one 3/8 line and no vent.the motor is far from original so I don't have anything running to the smaller line anyway,but will this be a problem for the tank or will it vent through the cap,
thanks for any help

Re: 69 fuel tank sending unit question

The tank will vent through the fill cap. The smaller fuel line was the overflow return from the 3-nippled gas filter in front of the engine.

The OE filter had inlet, outlet to the carb, and a return to the tank. This set-up aided in the prevention of vapor lock. The filter was/is mounted between the fuel pump and carb.
