I am in the finishing stages of a motor install on my Z28. Where does the oil sending unit go? I can not thread it into the holes above the oil filter area and that is where i took it from the old motor? the new engine is a mid 90's block? Any help would be GREATLY appriciated.

 

The oil sending unit on late model blocks is on top of the engine, next to the distributor. Most have a small brass fitting to allow more than one sensor to connect to the port.... One for oil pressure gauge and one for oil pressure switch.

 

Thnaks for all the help! Turns out that the motor was painted and the hole was pluged so we missed it but its all good now Thanks again!
