Julio/Alkycontrol i need some stuff and have a few ????

Copper is a soft metal that cracks easy. I wouldnt use it. You have a fire risk. Let alone these lines will be under a lot of pressure.

Solenoid, driver, 6 nozzles will be more than 175

There is space under the intake to place nozzles in the runners. Just saying.
why dont you use outside thread nozzles with pushlock fitings and run nylon tubing to the block
the plans revolve around the outside threaded nozzles.
After you and Julio replied yesterday i started looking at the push to lock stuff.
Worried if them lines might get bridle after a while.
i guess i can do some more research on the push to lock stuff before i start buying more shipt
