Oil line sizes

What are the proper oil line sizes for a 1972 750? Feed - tank to engine. Return - engine to filter to tank.

They would be 3/8 inch. Power steering return hose works well. 3/8 fuel hose will work for a while. Jim

I've been using the 3/8" NAPA transmission cooler hose. Sold by the foot. Even has the herringbone pattern on it.

Man, that "correct" hose Old Britts is selling... cha-ching!

Next time I need hose it's auto-trans stuff.
