dumb question I’m sure. But rather be safe than sorry. I have a proton plus system. And am converting from running the shark fogger to running a ls 90 mm plate. My question is...... I ordered all the fittings to convert from a -4an line to run a -6an line. How do I take the fittings off the solenoid. Do they just unscrew. And when putting them back on...... do they need thread lock to seal or should they be good

Yeah it’s in a single box so you don’t actually see the solenoids at all just the fittings
