Aftermarket sending unit not the same

i swapped to that sending unit in my dart when the original quit working. it seems to read full alot longer, then when it drops it drops like a rock. the empty line is defiantly empty....l checked that before i put gas in it


I bent the rod on mine so I had a bit of a "reserve" from E mark to actual empty in the tank, hopefully never run it that low but I also don't want it running out If it ever hits E before I get to a station
