Hello Folks, just an update on auxillary gauge fittings. As one was "mechanical" and the other "electrical", I've chosen to post in "Other".
Fitting the temperature sender was quite easy as the 1098 head already had a blanking plug fitted. As I bought the Gauge and Sender as a set (hopefully for accuracy), I had to use a reducer[frame][/frame]
I cable-tied the connecting wire to parts of the wiring loom[frame][/frame]
and then through the bulkhead via a gap alongside the loom entry (this will be seen in the next set of pictures when the copper oil pressure pipe had to be fed through.
Fitting the oil pressure pipe and adapters was a lot more time consuming as the T-piece adapter (to allow retention of the original pressure switch) was a bit stubby - I had to use some PTFE tape on the tapered thread to give it a tight fit at the correct orientation point. It took a few goes to do this - not a lot of room for my large hands[frame][/frame]
At the bulkhead end, the pipe with olive already soldered in and its fitting nut would not go through any existing grommet spaces, so I had to drill a 12mm hole (also had a tough time fitting a rubber grommet to the pipe).[frame][/frame]
Pipe, nut, grommet and hole in one pic - also note the blue temperature sender wire[frame][/frame]
Of course, I couldn't leave bare metal on the drilled hole, so I painted it with some handy Humbrol green enamel, I happened to have lying around[frame][/frame]
Pipe now passed through bulkhead and connected to rear of the gauge[frame][/frame]
The next image is of the pressure gauge showing oil pressure, engine "cold" and filled with the incorrect SAE30 oil which, BMC, I drained today and refilled with 20/50 oil.

and then settling down to these readings at tick-over[frame][/frame]
Question now is, are these readings satisfactory?
Regards, George.

All quite high readings! But well done. SAE 30 was the original oil specified for these engines - it would be fine I'm sure.

Good idea to paint the round the hole in the bulkhead, quality job.

Neat job ,well done

To save drilling the hole, you could have just cut the end offn the tube, pushed it through beside the wire and then refitted the pack nut w/a new olive.

Katy, I've got plumbing olives (for domestic water pipes - 15mm & 22mm) but nothing as small as this. The fitting ends were already soldered on (both ends) and, had there been a problem with the kit, I wouldn't have got a refund had I already cut things about.
On the nearside (UK passenger side, on the left), someone had already formed a hole for the radio arial, so it isn't the first additional hole, but this one was too far away for me to use with the copper pressure pipe.
Regards, George.

A superb job, but there really was nothing wrong with that 30 weight oil - you could have ran it until it was due a change.

The gauges, although of modern design, at least give an indication as to the health of your lubrication and cooling systems.
