Oil pressure sender M10

[Z00Z]

I'm replacing the "idiot light" sender with a real pressure gauge.  What is the thread specification?  The sender mounts at the rear of the cylinder head, just before the firewall.  I need the thread specification in order to replace it with an adapter to feed the pressure gauge.

 run both the light and the gauge. i think IE sells the adapter

There are two different thread specs, depending on the particular head/distributor flange you have.  Easiest thing to do is pull the oil pressure sender and measure the threads.  It is either M12x1.5 or M10x1.0.

+ 1.  on the two terminal sender.  And the adapter also gets the gauge sender unit (which is larger than the factory one just for the warning light) away from the firewall.  

 

BTW, the VDO gauge illuminates the low oil pressure light at 14.7 psi vs 7 for the factory sender.  So don't be surprised if the warning light comes on a little sooner once the gauge is installed.

I’ve had the VDO idiot/Gauge sender for 6 years so far

I installed the sender without the adaptor just like this 47 years ago and it’s still working.

I'm using the Bosch gauges; I also want to eliminate the idiot light so I need an adapter after I remove the light sensor.

I just used an adaptor so  both work. I have Speedhut gauges.

Thanks for the pic, do you have the mfg./source for that adapter?

Not trying to hijack this thread... but it appears to be the right audience. Where would I put the oil temp gauge sensor?

Here is one option, I think it is the same as what IE sells.

I went the oil filter mount that many do.

sandblasted the part and drilled n tapped.

Custom adapter for the M10.  Guaranteed to leak as much as any other with pipe threads.  Retired to the parts box.

Parts list:

1 used M10 pressure sensor gutted

1 nut retapped for pipe threads

some welding rod and sparks

2 bushigs

1 street el.

 

For the S14 I use a Bosch dual temperature/pressure sensor mounted on the filter head. Signals feed to the ECU and displayed on the Haltech display panel along with alarm messages and lights for low oil pressure and over temperature.
