guys just go in to your neighborhood hardware supply store and buy 1/8th tee and an adapter male/male

I highly doubt any local hardware stores have BSP fittings and definitely not NPT female to BSP male. Just everyone sit tight and I'll be the guinea pig on this. I'll tell you exactly what threads worked once I get the parts and my hands dirty.

Jordo!

So is about 10 psi per 1000 RPM normal?

Let us know what kinds of readings you see for hot and cold running conditions on the Z.

These are the gauges I have that will be installed this summer... don't know much about it. It should go for under $100. If you can buy direct, $35.

I'll definitely post readings when I get it installed. The service manual lists proper oil pressure at 15psi at idle and 40psi at 2k rpm.

I decided on the AEM Analog 0-150psi oil pressure gauge. I saw a youtube video of that digital gauge and the values jump around so much it's maddening. Both the digital number in the middle and the LED on the outside move all over the place. This would have driven me bananas....so analog it is. The AEM gauges have adjustable LED colors so you can match the interior orange too.

good stuff Alex, so is it safe to say that most oil pressure gauges sensors use the same thread? I have my oil pressure gauge for my Camp2 that I need to install still.

It sounds like US-made aftermarket gauges all use NPT fittings while most European and Japanese cars favor BSP threads for their sensors. My best guess is the HKS gauge is NPT and will require the same setup I listed above. To be safe and knock this project out in one attempt, I ordered all the fittings in BSP and NPT versions. So I'm covered regardless of what I find when I disconnect the factory sensor. It only cost me $10 instead of $5 to get the fittings in both thread types.

While I wait on the parts to arrive, I need to decide on which 12V switched source to splice the gauge power into. I'll check and post in the AV section, but ideas are welcome. If I install the gauge on the side of the steering column, I think I'll run the power under the knee bolster and tap into the 12V cigarette lighter in the armrest. If I decide to mount the gauge up on the dash (behind and between the 3-pod gauges), I'll tap into the other 12V lighter in the passenger footwell. Both are ignition switched I believe.

Why not just do the add a fuse thing from something on the fuse panel?

Because I forgot that was an option! Thanks Gene.


Does anyone know where you can find an add-a-fuse ATM-Low Profile version? Amazon only has ATM and ATO.

***It looks like the ATM version will fit in the ATM low profile slot, so it's still doable. These low profile fuses are stupid.
