330 / 275 | Source for ribbed rubber hose

this hose is not runnning from the crankcase to the oil filler. right, it is the crankcase breather but running from the oil filler into the free. sometimes people put a small canister to thje end of the hose to not drop oil on the floor. same system the 250 have, if in the front ( so the later models ) or in the center left and right

unfortunately you not filled out your profile - even here a member more than 10 years - so nobody knows where you are located and so nobody could tell you where to get those hoses

 

I´m just now as every year in thailand during the wintertime and will be back in germany middle of mai. I think I still have some of those hoses, but not sure. original they have been more clear, the changed color is because of the heat

 

Götz (and others in general),
It can also be helpful (to you) if you indicate more details and specifications of the item you’re looking to replace.
Listing things like I.D. & O.D. etc of the hose might be useful info to those not familiar with the given application.
For example, some one might have or know similar hose used in other applications, perhaps in Buick, Caterpillar excavator, Maytag refrigerator, so knowing dimensions and other specifications can be helpful.

 

NEWCO PRODUCTS in California offers that product.

 

Motion Products Inc. also offers this hose. I have heard it referred to as "Macaroni Hose" in the past.

This hose starts out as a clear hose with a "hazy" finish from being drawn through a heated cutter to give it the ribbed finish. Oil vapors turn it brown in color over time.

 

Motion parts far from the old Mike Dunn moulds.....good parts!
