All the suppliers I checked with like RGM, Old Britts, Clubman,,, etc say that the original heringbone patterned oil hose is out of stock. I want to replace my lines from the tank to the motor & back via the filter with some high quality and good looking hose. It seems like some American 3/8" ID hoses fit but not all do. Is it really some odd metric size??? Does anyone know of a good hose to use & who sells it? I want some good black hose, not the junk from my local Mcauto parts!
