Ok now on to tests. Testing fpr how long should diaphragm Hold vacuum for. My gauge pumps up but won’t hold and immediately leaksdown

diaphragms, do not leak at all

its bad, for sure. do not use this FPR again, like this, its hopelessly GONE FOR EVER this part, and will get worse and that is no place to be ever.
