    Vacuum nipple wrong side?

    I just bought a new petcock from CRCII and after a month and a half it finally came in. The prime nipple is on the same side as my original one but the vacuum nipple is on the same side as the prime. Which is opposite of the original one. Can I just take those 4 screws out and spin it around or will something be misaligned inside? My vacuum hose isn't long enough to reach around the other side without kinking.

    The diaphram is trapped by the backing plate held on by the screws. Its often NOT a good idea to break the seal from ..in my opinion. I would first try getting some more vac line and seeing if it can be routed differently as to not be kinked.

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

          Unless you eventually tear a diaphram breaking the halves apart..then it wasnt a good idea. Theres nothing but a spring in there as far as "loose" parts goes.

            Aaaaannnd this is why I ask questions before pulling something apart when i'm unsure. Thanks very much. Good thing my local motorcycle shop hands out free fuel line.

              I am still trying to figure out what the "prime nipple" is.

                Must be the big one in the middle.

                  Both the feed and vacuum fittings should point to rear on this model - I've seen 3 setups.
