How to hook up an oil pressure gauge

[Patrick Ertel]

I installed oil pressure and temperature gauges in my '56 coupe in the 70s. With few other resources, I found that 1/8 inch pipe threads are very similar to 10 x 1 metric fittings (pipe is 10.3 mm OD and 1.06 threads per mm). The threading process reduces the OD a bit. I wouldn't try this with a steel-on-steel fitting, but the threads on a 1/8 NPT brass fitting will conform and seal to 10x1 steel threads.

I made my own mounting bracket for the dash and used a 45 degree brass street ell between the 10x10 steel fitting and the gauge sending unit. Green wire goes the the "WK" terminal and white/red goes to the "G" terminal.

Does anyone make an adapter for 2-3/8” VDO oil pressure gauge? The straight threads on the gauge are challenge!

Sorry, did not understand your question.

Are you looking for an adapter to substitute the large "nut" ?

Or are you looking for something like this ?

Hugo, where did you find that groovy bracket mount for the two gauges?!?

Jim, I found the picture in eBay many years ago. I did not buy it.
I think it can be easily fabricated, something like Jim Liberty or Patrick Ertel did.
