Fuel tank vent tubes

[303 Mopar]

In the fuel tank vent tube that runs through the trunk floor pan up along the right rear inner wheel fender there are four vent tubes that basically run up inside the tube and end at different lengths. Does anyone know which one runs the longest/highest into the tube?

The only one that goes very high is the one that goes to the front of the car....

You have the M95 tube that goes in the trunk?  It has about about 4 nipples on it.

Yes - I remember that the 4 little tubes go up in the bigger tube and they all are different lengths. I'm trying to attach the vent tube for the tank to the highest tube.

Oh....  easy.  I'll go look for you.  Stand by.

You would have to cut the large tube open to find out. Why would it matter ?

I hadn't put the shield on yet so it was easy to take photos.

I get it now.     You're asking about what one INSIDE the metal tube is the highest up.  I took one apart a long time ago but I don't recall what one was longest.

When I swapped in the Tanks Inc. fuel tank it only has 2 vent nipples. So I ran those to to the thing in the trunk and looped the other two remaining lines. No issues so far.

This is exactly what I'm trying to do. I think I'm going to join both lines with a tee and run the remaining line to the highest tube.

That's what I figured why you were asking.      I would just connect them to the other 4 like stock. The tallest one as mentioned goes to the front of the car. I think how it works is, when the tank is full right up to the neck then when the fuel expands with temperature fuel goes into that tube thing in the trunk. The 4 lower ones it will then drain back into the tank when the level lowers. The tall one going to the front of the car connects to the air cleaner to burn the fumes so they don't vent to the atmosphere. I'm sure your modern Hemi will have somewhere to hook this in? The new cars are sealed so the fumes are directed into the engine to be burnt.
