We remote mounted the oil pressure sending unit in order to keep the weight of the sender off the aluminum block. We’ve seen blocks develop hairline cracks due to having heavy accessory set-ups mounted to them. It is always a better idea to remote mount these type of items. The local Earl’s retailer in Hawthorne, ANplumbing.com ,set us up with this 7 inch end to end line paired with a 90 degree fitting.
We threaded the hose to the sender and put some gold Kapton heat resisting tape on the hose to protect it from exhaust heat. We put the BSPT to A/N adaptor in a plug in the block near where the OEM dummy light sender went and screwed the hose to that.
Here is Vince installing the sender unit.
We secured the sender to the car using an Adel clamp and an existing bolt.
Now we had to route the gauge wires into the car’s interior. Vince uses a drill to make a hole under the cowl cover through the firewall. Several other things pass through the firewall here so this was a good, protected spot to do it.
The hole was drilled near the base of the windshield.

The thread type should be called out as BSPT, to differentiate from BSPP. BPT is an incomplete designation. It is interesting to see the British influence on Japan carries through to this day.
You are very bold drilling a vertical hole through your cowl into the driver’s compartment. Here in the northeast I would be very concerned about water intrusion. I’d be filling that grommet with RTV or some other type of sealant.
I stand corrected, upon closer inspection, it looks like you may have a BSPP (parallel) connection that seals on the face rather than a BSPT connection that seals on the threads.
It is actually not a vertical hole, it just looks that way in pictures and its near other OEM pass-throughs.

I installed my Oil Pressure and other gauges the exact same way. I was feeling kind of insecure thinking that there could have been a cleaner way to do it (of course there is), but knowing that others have done the same makes me feel validated.
Are these more accurate than an OBD2 gauge (scangauge, plx dm100, etc) ?
As accurate.
Where did you guys get the 1/8″ bspt to -3 an adapter from? I am having a hard time finding one! If you have extra, can I buy it off you guys 🙂 I’m local to socal.
