Im thinking to upgrade the stock 6mm(1/4) lines to 10mm (3/8 aprox) since my lines are little long, in theory this will free some pump pressure (right?) also Im going to install a dual nozzle setup.
What its your opinion on this.
Thanks.

 

6mm line will be plenty big

assuming you running 2 X 1.0mm nozzle, the combined orifice diameter of the 2 atomizing nozzle is much smaller than the ID of the 6mm tube. You will not be limited by the line

 

Thanks for the responce ... Im installing 2 m8 nozzles with the stock 6mm lines.

 

a 1mm nozzle would be equivelant to about an m7.3 if they made one. What I'm getting at is, the flow from a 1mm nozzle will be slightly less than an m8, but in the ballpark. Regardless, the 6mm line will have about 1800% more cross sectional area for flow, so like slowcar said, I think the line size should be sufficient.
