I'm asking about my 440+6 and the right side bowls on the rear 2 carbs.
The fuel line is in the way and I can't get my wrench in there. I've managed to reach the
other 10 nuts, but these 2 are the most challenging.
Do you have to get to them from the left side? If so, that seems a bit difficult.
Of course, the carbs are on the car.
 
The top one should be no problem,the bottom you will probably have to remove the fuel line.Why are they loose to begin with ?

I should have mentioned I was having a problem reaching the BOTTOM nuts.
I didn't see any leaks, but am smelling strong gas fumes in the garage after taking the car out for a drive.
I tightened the 10 I could reach just a bit. Each one was equally "loose".
The fuel lines are nice and tight.
Just trying to track down the cause of the raw gas smell after a drive.
 
I can get to my rear carb's lower right side screw with an open end 5/16" wrench. As far as the same screw on the center carb you may try grinding down the open end wrench (on the outside edges) for clearance and possibly heating it with a torch then bending it slightly for the right angle. Haven't tried it but I think it may work.

Edit: Just out of curiosity I decided to try my own advice and this is what I found; forget about modifying the open end of the wrench, instead work on the boxed end. I heated up the wrench's neck in two different spots and made a couple bends to be able to access the head of the screw from in front of the fuel line on each carb. I also ground the neck so it was narrower for better clearance.
This worked fine on the rear carb, but I had to remove the vacuum unit on the front carb to access the screw on the center carb.
This didn't take long at all and I didn't have to mess with disconnecting fuel lines.

Smelling gas fumes after a drive is pretty normal with today's gas. Carbs hate that stuff and what is happening is just evaporation. The carb heat soaks because it has no fresh fuel running through to cool it down, so once the engine is stopped the temps equalize. My HEMI Charger does the same thing. The perfect solution is fuel injection.
