FineOlBenz,

At highway speed the engine spins at about 3,000 rpm or so, which means 1500 injections per cylinder, per minute, or 6,000 total per minute, or 360,000 per hour. In an hour at highway speeds you use roughly a gallon of fuel. So each spritz is about 1/360,000 gallon. At idle it is even less. So don't expect a gusher from the injectors.

If you have loose connections, the fuel lines will allow air to enter, especially when the engine is shut down. As the fuel leaks out, air leaks in. This can get into the pump and cause the pump to get air bound. Basically the fuel is not a compressible fluid and air is. Since the pump was designed for fuel, it does not work right on air. So, tighten the fuel lines carefully.

Good luck, Jim
