Thats fine for now. Remember though that you must turn the petcock from PRI to ON or RES when you stop the engine. Also remember that you have a disconnected vacuum line. This may cause irregular running, lean conditions, and exhaust popping. Consider plugging the other end of the vacuum line (where it went into your intake manifold) to temporarily correct this problem, and replace the line as soon as you can. You can do this by taking a short length of hose, tying it in a simple knot, and plugging it into your vacuum nipple.
