1994 Jaguar XJ6 • 110,000 miles

Where can I find a fitting to check the fuel pressure on my 94 jag xj6, which is a 14mmx1.5 thread. There is no port, so I have to tie into the fuel line at the rail. My gauge is a standard one I use for my chevy truck which is SAE, probably 1/4". Some inexpensive solution would be great. Going the way of EL08LA3C, VKAS08LA3C, MAVMD adapter, etc. Seems a bit extreme. I've tried to borrow one from a quality foreign car repair shop, but the flange on the connector wasn't flared enough to get the threads close enough to grab hold at the rail.
Hope you can help
