Title: Oil Temp gauge sender unit location
Post by: Europa73 on Monday,March 05, 2018, 08:47:42 AM

Hi all,


I am thinking of attaching an oil temp gauge.

The question is - where would I attach the sender unit?

Cheers,

In the absence of an oil cooler, the only place I can think of is in the sump.

You would have to take the sump off, drill a hole, braze a brass connector in the right place where it would not be hit by the crankshaft, and put the sump back on.

That's where I put mine.

I brazed a bung onto the oil pan (off the car) then tapped the bung for 1/8" pipe thread to match the sender's thread (yours may be different).  ...You can also use an appropriate pipe fitting.

The sender threads need to be sealed with pipe dope, or Teflon tape to prevent leaks, but that inhibits a good ground connection.  ...To prevent this, I soldered a ring-style wire terminal to the brass sender.  ....A short wire attached to the sender and a convenient grounding point on the engine restores the integrity of the ground circuit.
