Yeh, on your first pic, pull the hose off the brass block and check for vac. (with eng. running) there, or just under your check valve in pic #2 middle arrow. It needs to be more than just pulsing your finger tip. It should stick you finger to it. I just ran out and tried mine and it pulls tight to my finger. Another option for electric pump is a ford super duty vac pump from autowreckers . pt

Mine done that too. i just unhooked it from the vac thing that opens and closes the lever to switch it from defrost to dash and zip tied the lever in the down position for a temp fix till i have time to troubleshoot it so it would blow out the dash

You can pick up the vac line at any parts store. I know pep boys has different size line by the foot.
