Ok, limited experience here hence the following question....

Are oil pressure sensors similar to fuel gauge sensors in that the sensor needs to be matched to the gauge?

The reason for asking... The oil pressure sensor that came with the autometer gauges is huge and wouldn't fit into the 302 block without some extension/adaptor. Went to the local parts store and ending up getting a new sensor compatible (supposedly) with 1990s Mustang. However, this sensor pins the Autometer oil pressure gauge above 100.... So I'm wondering if it's a compatibility problem

Thanks for the help
