There are two types of senders for sure if not more for a 4450. I believe there are two senders for the investigator II digital dash and one different one for a mechanical dash on earlier models. you MUST get the right one of there will be malfunctions or misreading really should try a mechanical gage to be sure you have good oil pressure.
