On my 1973 Spider Junior (1600cc engine) the oil pressure gauge goes off the scale (high) whilst driving. It sits at 4.0 bar when idling. Reading the various topics on here it points to the sender,as earthing it makes the gauge show maximum. So I need to order a new sender I guess. Problem is the current sender has 2 spade connectors (only one connected) whilst the replacements shown on the Alfaholics site shows only 1 connection. This makes sense as I believe the gauge is always live so only need one connection to the sender. The gauge is Veglia. Can anybody help with replacement sender I need to order as I understand fitting wrong/incompatible sender can cause problems. I guess as the existing sender has the 2 connectors this points to it being the wrong type.
