different kits & styles use different sizes. 16 fogger lines are smaller than some of these monster plates. PM some of the sponsors and tell them what you're trying to do, so you get the correct balance. Good luck.

We use 3/16 on the hardline from the distribution block to the nozzles on a directport.
We use the same 3/16 on a single nozzle or efi plate from the solenoid to plate/nozzle.

On the fuel delivery from the shrader valve to the solenoid we use 1/4.
Feel free to get in touch with me to tell me exactly what you are doing and Ill tell you what to use.

On that system you can use 3/16 from the solenoids to the plate.
