I have managed to find an original Eureka oil pressure gauge and now being fully restored by Speedograph.
Now I am wondering what connection do I use to get the oil pressure feed from.
Any thoughts gratefully appreciated
I’ve attached some pictures from my 1952 Model 7. It came in bits and I haven’t got round to this yet. However I think the pressure gauge feed comes from a banjo bolt on the back of the timing cover. There is a fair length of copper tube which heads up towards the petrol tank. Then there is a connecting piece of tubing joining that to the gauge. This must be so you can connect / disconnect the gauge.
Obviously the tubing has been bent from the correct shape over the 55 years it’s been sitting around, but hope it helps.
By the way how much is your gauge rebuild costing? As you can see mine is in a poor state and I’m not sure what to do with it.
Here’s my gauge Can only add 4 files at once
That gauge has some serious patination, I love it.
Patination vs function.
In a much newer maintenance manual P106/P side 12, it says that "On the SS models with the old type timing cover, there is a 5/16" BSF set screw below the relief valve and a pressure check can be made from here using a rocker box banjo bolt which have the same thread, and a suitable banjo with which to connect the gauge."
Hopefully same thread on a 7.
