The arrow points out the original factory sensor for the "Idiot Light" that was originally the only item installed in this
place on the engine block. It is screwed into the 1/4 NPT to 1/8 NPT reducer that came with the filter kit. Make sure and
use the thread sealing liquid provided with the filter kit and not teflon tape to seal the threads as the sending unit needs
an electrical ground in order to work properly and teflon tape will prevent this ground from being possible.
