Like @4Cruisers said, you’ve got extra hose you don’t need.
here’s your photo with my numbers:
1 - remove this cap. This port needs to be connected to vacuum. The distributor cap has 2 ports. One supplies clean air. The second (you have capped) evacuates air. It needs air flow through. Your supply hose appears connected properly - It goes to a port on the firewall. Your other hose is missing.
2 - pull the hose off the outer and cap it. This is the high altitude advance port. If you ever travel to elevation - you can switch the single advance hose you have on the inner port to the outer - assuming the advancer still holds vacuum
