Make sure you are using a thread sealant or teflon tape on the threads and never tighten the sending unit by it's "bell". Always use a wrench on the hex portion behind the bell when tightening.

Don't use Teflon tape. Only Teflon sealing compound or pipe dope. The threads are too fine for tape.

And DO NOT overtighten, because you can crack the rear iron.
