Well i have been working on my 73 240z for about 6 months now.i traded of my sportster straight up for it.and i love the car,but know nothing about them.i have been buying parts here and there..im not trying to get it perfect yet.i really want to have some fun with it first.my son loves to drive it and it makes me happy to see him take it.i think the yonger ones need to learn a little about the vehicles that we learned to really enjoy.well i could go on so i will get to my firsts ? I have been tuning my carbs and think i am zeroing in on them.the ? Is about the lines that can be pluged and the ones the need to run into the air cleaner.it has after market (longflo) filters on it now.do i run the vent line from the valve cover into one of the filters or t the line so it will go to both,and the 2 lines one from each carb...do they also need to go in to the filters..and i dont know what the one that runs to the diver side of the frame is for..im thinking its a vent line for the fuel tank.i know this car is not stock and it has a l28 motor in it,not the l24. It also has a cam,so i am dealing with that also.i have attached a befor and after photo............nice to meet you all...hope some one can help.

Thanks again,matt

Welcome Matt (that's funny):

The line from the drivers-side wheel well is the flow-guide valve. It's not a vacuum line, but a vent for fuel vapor. The lines from the top of the float bowls are vents as well.

I believe there are openings on the back-side of the filter element mounting plate that you can run these lines into. The problem with the open holes is that dirt can make its way past these holes and go directly into the carbs. For that reason, I'd install some sort of nipple for the vent lines on the back plate.

For several reasons I'm not a big fan of the Longflo pods. There is the open back plate I mentioned above; and there is the lack of the air horns. The air horns are an important part of the carb design. Truth be told, the OEM air box is the best design for the SU carbs.
