Default 1978 928 fuel accumulator leaking from screw at top

Just as the title says. My fuel accumulator is leaking from the flat head screw at top. I’m working on getting the car running. Got new fuel hoses installed, ran the fuel pump and it’s spraying a fine mist out of the top of the accumulator. I removed the screw, reinstalled and tightened it - still leaking.
I searched the forum and didn’t see anything in this issue. My initial idea is to put a fuel safe o-ring on the screw.





Any suggestions are appreciated.

Diaphragm in accumulator bad.
You need a new accumulator.

Thank you Greg. - not what I was hoping to hear, but it is what it is. Hopefully it’s still available. Thanks!

Should I get the same part number that’s currently in the car (see photo showing number)? When I Google that number it says mine is for a 911.

The proper size fittings on the proper ends are what's important. A few years ago I had a heck of a time finding the one I needed. Hope you have better luck.

Take a side view picture, so we can see which one you need.
