Oil Pressure Gauge Adapter (BSP & NPT)

osbornsm

I've spent a lil time researching the necessary parts to install an aftermarket Oil pressure gauge.

Note: This is not a DIY

• This is only here to inform the community which adapter is required for an aftermarket Oil pressure gauge.

The engine is BSPT, threaded. NOT BSP.
See that "T" makes a big difference.

Refer to the diagram below ==>

Here be some results.

...and yes it dims with the gauge cluster.

Where did you get the adapter at?

The only place i found one available is here:

Oil Pressure Sensor Adapter, 1/8" BSPT - Engine - Autotech Motoring

Don't forget it has 2 x 1/8 npt holes, so you'll have to plug one of them.

Just about to install an AEM oil pressure gauge. According to the install instructions, it appears the wiring from the gauge to the power supply is similar to the Defi gauge set-up. Based on a quick look, I've located circuits in the interior fuse box located on the driver's side wheel well for the switched and unswitched power that's needed (which I can link into using add-a-circuits). What I need to know is what wire can I tap into so that the gauge dims with the gauge cluster as yours does. Appreciate any help you can provide. Thanks!

I have a spare AutoTech adapter (complete with plug) if you're still looking for one. $25 (including shipping) and it's your. Post me if interested.

Thank you. i was just look for this

I was only able to find a dimmer wire as part of the radio harness wiring. Luckily, one of the radio wires was tagged with "ILLUM" and i spliced into that one.

Well, that was convenient. I'll check the wiring diagrams in the full service manual and find one to tap into. Thanks for the reply!

Do you ever go over 100 psi?

osbornsm

Reading old thread, thought it might be nice to bump it up for noob's.

And for reference, it stays below 100psi when the oil is 180F. Until then it's possible to get up to 110 psi, which is not the healthiest.

Can I find this adapter at the HW store? I was going to install my gauge this weekend but my sandwich plate doesn't have a port for the gauge. So I have to T the stock sensor.

I know I'm quoting an old thread, but I finally got the adapter that's drawn here, so BSPT thread in and out, and another 1/8" NPT inlet for my pressure sensor. One maybe stupid question - on my pressure sensor the thread is indicated as 1/8" 27-NPT. This "27" is saying the number of threads per inch from what I can tell and if I'm not mistaken, there is no other option, so this *should* fit the thread in the adapter. Anyone know more? When I try threading it with hands, it goes some 3 threads in no problem.
And that's my second question. Any torque spec to this? I don't think I can thread it *all* the way in. In fact, it looks like if I tighten it to about 7-10Nm, I will probably hit the lower limit of the thread hole, so that I don't obstruct the oil pressure flow inside the adapter. I think that actually answers itself.

Thank you!

EDIT - Managed to google out the answer. Apparently the torque spec is with teflon added - from finger tight, another full turn or two. Careful not to overtighten.
