The cheap single stage pumps really struggle to get down there. The quick/easy thing to try is better vacuum pump oil like black gold. I’ve taken one of my single stage pumps apart and surfaced all the critical sealing edges, cleaned well and reassembled. It made the biggest difference when getting down in the low micron range.

The plastic cap by the inlet hose wasnt on all the way and was leaking on mine. That was the fix.
