oil temp sender

For my '74 Duster I bought a brass tee and a threaded nipple/pipe from Lowes. I used the Oil Pressure Sending Unit for a Dodge D50 (small in diameter & height) on the Tee to gain some space. It's about 1/8th the size of the stock canister and operates on the same ohm range.

On my '84 D50 I didn't have enough space to fit a sending unit at all, so I ran a copper oil line from the sending unit port to the fenderwell, installed the Tee, mechanical gauge line and sending unit.

If you take the approach I used on my D50 don't forget to mount/ground the Tee to metal.
