water temp gauge on a RPM II

I have a performer RPM II and I use an Autometer sender and temp gauge. Once I installed the intake the stock temp sender took a dive on me. I have gone through two temp senders from Autometer because the last two leaked on me. I tightened them as hard as they would go and put sealer on them but they leaked from the sender. They fit fine though, so did the stock sender. I guess I would recomend getting an autometer gauge.
good luck and sorry I can't be of more help
