Sounds like your lift pump diaphragm is split allowing the fuel to enter your engine. Remove the lift pump (just below the injector pump). Attach it to the fuel lines and squeeze the primer bulb and see if any fuel leaks from the end (this will pressurise the fuel lines and help show any leaks), if it does you need a new pump. The only other place it could get in the engine is the injector pump but its more likely that its the lift pump.
