So confused

[Jerry1]

I have a few questions. I have a 901\38 6404302 long block. I believe it is a 1969 914-6 I am trying to close up the block I am confused about which temp sender and oil pressure switch to use.

First off the oil pressure switch I got the threads are a smaller size than the opening do I need an adapter or do I have the wrong one



Next the oil temp sender I ordered look like it will thread in but I don't think the probe on the sender will fit there is only about 1 1/4 of an inch total clearance I didn't purchase it I was hoping to get some clarification. I noticed in the book that the sender mounted vertical not to the side.





One more thing did this motor come with the updated oil bypass or has this one been modified here is a picture of the piston that I took out of the bottom, opposite the oil pressure hole.




If anyone could help I would greatly appreciate it
Thanks Jerry

The bell style oil pressure sender 0-15 atm or there is a fitting that the idiot light switch screws into. What you have is a 7lb on/off switch right above the oil pump with your switch.
Temnp sender in the second pic should be a gold color with a slip on T for wire connector
The pressure relief is the later model style from the update.
