I’m looking to rebuild the line to my oil pressure gauge and create a 2nd one for back up/emergency failure. Does anyone know where to purchase the original BSP fittings? I’ve seen the stainless lines available from the usual vendors, I’ve looked in the JL archives, followed some leads to hydraulic fitting shops and visited a few places that make hoses. Nothing available so far. Anyone had any luck with the exact fitting pictured below. Or, will I have to by a repro stainless line with fittings attached from the usual Jaguar vendors?
I’m not trying to be funny here at all Bruce, but what that picture says to me is “buy a lathe”. I did. It is an incredibly useful tool and both fun and immensely satisfying to work with.
I’d offer to make you some myself but I live in Australia which probably isn’t convenient. I’d suggest getting in contact with your local model railway enthusiasts club. There will be a dozen friendly old guys there who could make them for you easily.
I like the idea of someone making one or two, maybe on a CNC machine. I might see if my nephew knows how to use his university engineering department CNC machines. I might have another CNC source but, it is an active business and it would probably be necessary to have my CAD design ready for the computer so I can be in and out of their shop.
I don’t know much about engineering, CAD or CNC.
My fitting has 28 tpi on the gauge. I believe that makes it BSPT 1/8 28 tpi. Does an engineering drawing or CAD file exist for this fitting?
Bruce, correct name this time.
To be precise quote thread rate and dia
to a machine shop.
Don’t confuse the conical seat for the
connecting pipe with a tapered thread
which in this case is parallel, not BSPT

Ahh, ok if your goal is original appearance I understand perfectly.
I don’t know that anyone has attempted to trace the history of the development of that hose from the original unshielded rubber to the present day braided shielded version, but brass braid shielded was the standard version available in about 1970 when I first needed one on my Mark V.
As to concours, I suspect most cars on the concours field will have a new replacement, and the judges will not be aware that there was ever any other version.
