Fitting an Oil Pressure Gauge to a TR7

Fitting the gauge was quite easy, I used a 2" mechanical Smiths gauge, this is the same size as the clock which it replaced.

I actually bought a second hand instrument pod off e-bay to use for fitting the oil pressure gauge to and I also swapped the speedo for my original. So I can always put my original instrument pod, which is still intact, back in if required.

The steps are,

1. Remove complete instrument binnacle, disconnect speedo and all wiring plugs.

2. Remove clear plastic binnacle front and then the black instrument shrouds. (see photo)



3. The clock can then be removed, it's only held on by a couple of screws at the back. (see photo)



4 Fit in new oil pressure gauge, I had to trim away some of the white plastic at the rear of the binnacle to allow for the capillary pipe connection, also I had to drill a couple of holes for the gauge securing studs (see photo).




5. Reassemble the binnacle.


6. Fit the capillary pipe connector to the engine block in way of oil pressure light sensor, if a T piece is fitted you still have the oil pressure light. (see photo)



7. Run capillary pipe from engine to gauge thro the bulkhead and connect up both ends.

8. Refit the binnacle and away you go
