fuel sender, right or left?
 

Hello guys, i hope you are doing great, i finally got my differential replaced on my 1996 c220 with manual transmission, but now the fuel gauge stopped working, at first the needle was " dancing" a lot, but eventually went down.
i want to get a new fuel sending unit but found out the car has 2 of them. the question is, wich one should i get, the left or right side? or both of them?
also another question.- Does the low fuel light indicator will continue to work even if the needle doesn't? , i don't want to get stranded on the road.
Thanks in advance for all your info
