Ok, so for the fuel lever sensor (put image up again) is the silver tip supposed to be able to move in and out of the black cylinder? Also, what's that red stuff that also got on my hands. It is sticky/gummy. Is that some sort of sealant to prevent gas seeping from where the unit attaches to the tank? If so, any ideas what type of sealant it is so I can reapply before connecting the unit back to the tank??
