I purchased an universal fuel sender from our hosts and I am not sure if I assembled it correctly as the fuel gauge reads full when full, but empty when it is at half a tank. The little clips allow the float to spin on the rod that is connected to the sender. So I am not sure if I installed the sender correctly to bring with.

Is there a way to adjust or a trick to assembling the rod that connects the float to the sender? Any tips would be appreciated.
