When you do replace a sender or a mechanical gauge make sure you install a needle valve or a snubber before the sender or gauge to protect it from water hammer damage which is most likely the problem here...

Mechanical gauge are in the long run more durable compared to electric gauge that tend to wig out without notice... Plus theelectric sender are expensive to replace all the time...
