Mark,
I have had decent experience with Kirouac Fluid Industries in Ottawa making custom length/fittings brake flex hoses. 613-742-8593. They claim to be able to get pretty much any fitting made and be able to make whatever length. I don't know if they have the restrictor fittings for the bypass filters.
I've been told that similar service should be available from Diotte's Hydraulics. I'm not sure who does the same type of work in the West end if these are inconvenient for you.
