Few days ago I replace a short rubber hose and inlet fuel filter because the rubber hose was leaking fuel. The car previously ran well after I replaced it and now fail to start. I can hear the pump start when turn key on, the car will cranking a second but fail to start, sounds not enough fuel is being sent to the front. A friend told me it need air out by letting pump run and circulate but I didn't know how to do it. Any hint I should look into before tow it to a shop which I believe its a small fix.
