I don't have any canisters but without the return hole I can't think of any plumbing method that would reliably do exactly as you need even with a different unit.

One thing worth trying is to pretend the car didn't have the filter and plumb around it for a test. Use a short length of tubing as a pigtail to go directly from port to port as was done in all the cars without filters. See if the noise goes away. If it does then plumb the filter and drill the return hole per the bulletin. You could keep the canister unit you have now in operation. Napa has short lengths of premade 1/4" steel tubing with the proper flares and american thread nuts that you could bend to go from the tee to the straight adapter fitting to use for a test item.

After a few minutes running, if the noise is still present then you have something else going on that needs to be resolved. Maybe a bad lifter or maybe a chunk of something passed thru when you cleaned the filter and is now lodged in a lifter so one or more need cleaning
