I am trying to figure out the RIGHT adapter I need for putting my old Oil Pressure sensor on my new block. The adapter I bought from speedway motors isnt even close to being right. Anyone have a reference to the correct one or know the thread sizes?

18mm male and 1/8 NPT? Little bitty fitting for the OP gauge, right? If not then you have the one that is 3/8" NPT. Is it too small for your sender?
My adapter is to small on both ends. The end that screws into the block is to small, and the hole that the sensor screws in is to small. so the sensor wont screw into it.Quote:

And the stud on the sensor is a big guy. looks like its 3/8.Quote:

These are the sizes available from S&P that are a little more expensive. Click the pic to enlarge.
if it's 3/8 on the end it's probably a 1/4" NPT. Go verify size before ordering another one.

Wanted to update everyone with what I did. Since the hole on the motor is 16 mm MALE, and my OBS sensor is 3/8 male ( that screws into female) the part i bought from speedwaymotors was wrong because it was 16mm male x 1/8 female...so what i did was went to napa and got a 1/8 male to 3/8 female adapter for 4 bucks. worked great. so i basically have 2 adapters on top of eachother and then my sensor, but it works and i can have the sensor so its sticking straight up so its easy to tighten (unlike when its on a 90 degree angle and it hits the firewall when i tighten it)
Does anyone have good pics of these installed? Are you using an existing hole or tapping new? Where?
I used the hole right on the back edge of the block.Quote:
