Good day folks. I surely hope someone out there will be able to assist me. You see I've been working on a check engine light for quite some time to finally realize that I had a bad vacuum leak. It was due to bad seals mounted at the end of these vacuum line you see in the picture. I tried "O" rings but due to their shape will not stay in the groove designed for the seal. So I ended up using vacuum connectors with a piece of hose. It works but I'd rather have it as the factory intended. So any ideas of where I may locate those seals? Thanks in advance.
