To test the boost solenoid can you have the ignition turned on but the motor off. I connected the vac pump directly to the diaphragm and it held vacuum fine. I connected it to the hoses going to the solenoid and it leaks down immediately. Still need to confirm hoses are ok. But is this how you test the solenoid

Don't need the ignition on.

Sounds like there a vacuum leak somewhere. Cracked vacuum reservoir? Port at hose #1 (in first image - #1b in second image) should hold vacuum. Not sure if the hose itself (looking back towards the vacuum source) will hold vacuum but assume it would too.

Here's a bunch of info on vaccum line routing: -

Also some info on the operation on the boost actuator...
