Hi. I have a 1972 Thunderbolt. This engine has the oil pressure switch fitted. Does anyone know where i can buy parts to fit a Oil pressure Gauge, in place of the OPS. SRM sell Gauge's but no fitting's. Any advice on how to proceed are welcome. I would prefer to buy a ready made kit but I cant find anything outside of the USA.
Thanks
I bought all of the parts required from here:
http://www.vehicle-wiring-products.eu/product.php/210/oil-pressure-gauge-capillary-type
They also supply a capillary extension kit and T-piece.
Send for their catalogue.
I will send for a catalogue. Not sure what the T piece is for? adding something extra I presume,
Thanks for the info.
I use one of the T-piece outlets for a connection to the capilliary tube, the other for the oil pressure switch.
Thanks for that. I will do the same.
Should you intend to use the pressure gauge as an instrument whilst bike being ridden rather than as a workshop diagnostic tool you may wish to consider how to isolate the copper capillary from engine vibration and possible fracture.
A fractured pipe, which is situated between the pump and the crankshaft, would likely lead to a catastrophic engine lubrication failure.
Service sheet below from BSA gives a pressure figure.
Put a loop on the capilliary pipe so that there's no tension on it.
Vibration is the enemy.
The oil gauge would be a permanent fitting. Thanks for the vibration warning
My copy of the Vehicle Wiring Products catalogue, admittedly several years old, lists the gauge as not suitable for motorcycles. I would suggest checking with them before fitting.
Have you seen this Morgo item? Comes with flexible connection rather than metal tube but I dont know how it connects. I have found Morgo to be helpful if phoned.

Hi,
A few photos of mine, I used plastic pipe such as this

The gauge is glycerine filled to reduce vibration fatigue. A folded stainless plate fitted and secured under the clocks.
Best wishes...
Hi. Caulky. JulianS. & Bess. (Your Gauge set up look's good.) For all the Information & links provided. I have enough knowledge now to proceed. I really appreciate everything posted.
Thank's to you all.
Hi Boneidle,
You're most welcome, good luck.......Bess...
