I have Tim's setup on my 81, tested mine up to 200psi - no leaks.
Not terribly uncommon to do this. My replica cobra has a mechanical oil pressure gauge, so it if ever leaks, that's hot oil behind the dash. Yes I'm looking at options to change this.

im still trying to figure out why mine is leaking. Its ok for quick tests, but its a "drip ... drip....drip.. " kind of leak, no matter how much I tighten it up.
I have the "O" ring installed as well. im thinkining the nut might be bottoming out on the fuel rail housing, and is keeping me from the last 1/4 turn of cranking.

any thoughts?

As anyone heard from Tim Murphy lately? I was hoping he would chime in on this thread. I would like to buy one of his fuel pressure gauge adapters. I tried PMing without any luck.

the gauge and adapter are sold by Carl:

I had a friendly machinist drill-and-tap the rounded end of the test port cover nut for 1/4npt and machine out a recess for the o-ring (he looked up the appropriate dimensions in some machinists' reference book) on the metric end. Same idea as Carl's, but starting with the original nut instead of brass hex stock.

Thats what scot and i did . (or started to do) Never got around to drilling the extra nuts we bought from 928intl to have them drilled out and tapped for the hardware we bought for accepting the fuel gauge or the fuel test port we need for SCCA.
I was worried about using the threads to seal that vs what you did with your machinist, carving out an "o" ring area.

Bump for Tim Murphy.

Trying to contact you about a fuel pressure gauge adapter through email and PM.

Do you have one for sale?

Thanks
