The oil lines on my BSA are 5/16", but the spigots on the oil filter are 3/8". I can't change to 3/8" hose, because all the fittings on the bike are 5/16". It looks like the fittings on the oil filter are not removable.
I can get the 5/16" hose onto the filter, but it's a "stretch" (literally). It's not pretty but I guess it'll work.
Is there some other solution to this problem that I'm not seeing?
(BTW, the blue is masking tape. The bracket will either be painted black or remade in stainless steel.)
