1987 740 GLE -- Vacuum Canister Shot -- can I improvise?

Symptom:
Air coming out of A/C vents very weak.

Diagnosis:
I traced the vacuum line through the firewall and to the T fitting
where it splits through the vacuum check valve and to the intake, and
the other direction goes to the vacuum canister.

tested it, then cut the ends and reassembled everything on the hoses.
This is OK.

I removed the vacuum hose from the T-fitting to the vacuum canister,
checked to see no-body was watching and attached my "pulmonary pump" to
the vacuum hose. (I blew into the hose).

The air flowed freely -- something was shot. I looked and looked and
could not locate the canister. Correction - I could not ACCESS the
canister. So, at the T-fitting I sealed off the opening with electrical
tape and tested the vents. Great air flow - it worked.

So, now what can I do about the canister? Can I buy another one, mount
it somewhere else and run a new line?

Thanks!

 

I had to unseal the end of the T-fitting that goes to the vacuum
canister. It seemed to be choking the motor. When I unsealed the
T-fitting, the motor aspirated better, but I lost my ventilation
pressure for the A/C. I am guessing maybe a canister from AutoZone?

 

Regarding the above, I have no idea how to access that bugger. I got
under the car and it looked like I needed to remove the bumper on my
740 to get to the canister.
