2150 carb with 1 in 1 out fuel filter

Just installed the 2150 carb on my jeep but was wondering about the fuel filter setup. The orig. filter is 1 in and 2 out but I opted for the 1 in 1 out that screws directly into the carb. Was just wondering what to do with the extra fuel line now. It appears to run back to the gas tank. I have capped off for now. Also the electric choke has a opening on the side that I assume is for warm air. Not sure where I should run that. Otherwise I now only have the PCV line running to carb, the vacuum advance, and the one line from charcoal canister that vents fumes out going to float vent tube on top of carb. Does that sound about right to you guys? I have done the nutter and TFI upgrades. Thanks!

You should have the 1 in 2 out filter on it. The mechanical fuel pump produces way more fuel than the carb actually needs and the 2nd line relieves that extra pressure and sends it back to the tank.

If you leave it like it is, it will shorten the life of the needle seat on the float in the carb, as well as the fuel pump.

All the rest that you described sounds like its ok.
