So the problem in line 5 is that valve. Can I just disconnect it from the canister and leave it open?For those who are a bit more visually minded here is a CAD image from the service manual showing where to cut and block the hoses.
To block the vacuum hose I used a $0.68 dowel rod from ACE hardware and a couple of small hose clamps. It's similar to Godfrey's method but using hose clamps rather than glue to secure the plug/dowel.
Thanks for your guides, Godfrey.
