Before reinstalling the new unloader, reapply teflon tape and the appropriate color of thread locker.

Apply the thread seal tape in the opposite direction of the treads so that it doesn't unravel when you screw in the fitting. Wrap the tape around the fitting about five times.

Both of the plugs need red thread locker. Both of the nozzles and the fitting going into the bottom of the unloader need thread seal tape and blue thread locker.
