At this year's annual I decided to give the old faithfull O320 A2B a treat and bought an STC'ed Casper Labs filter adapter. Problem is that my engine (late 1958 model) has the paired oil steel lines and after more than $500 invested (filter/adapter/adapter extension/alternate K&N filter etc) I cannot clear the canister and/or the housing. The left line (return) can be cleared but the right line is always in the way...

Has anybody solved this problem legally?
I am fast becoming frustrated and need to get this resolved quickly.
