I went through the winter with a weak starter and replaced it a month ago with one I rebuilt and no more starting problems so I have time to deal with other issues such as boost.

I tried adjusting the Alda, had it fully C.C.W. and still getting max 9 psi. I then pressure tested the Alda aneroid and it would not hold pressure for very long. I pumped it up with a mini bicycle pump to 15 psi and it would leak down to 0 within 5 seconds or so. Should it hold pressure longer than that and how much longer?
I had shaving cream around the connections including the banjo fitting at the aneroid and saw no bubbles so I am pretty sure the aneroid is the part that is leaking.

What should I be doing next?
