Greg built my Vintage speedster, and it had the push on hoses to the same fittings you have. Greg said they would be fine. After you posted your photo, I went out and bought the appropriate-sized clamps and installed. The top clamp onto the hose of the added oil cooler I requested for the build t ook a little arm-stretch work, but I am 100% in agreement with Theron. 4 clamps, $4 bucks, 30 min. install vs $$$$ for a new or rebuilt engine. Peace of mind. Priceless.
