The clamps at the cat busted it off so it already had that gap, so to further prove that I took the cat back exhaust off including cat. Still no change. How do I check the transducer or waste gate and where are they? Thanks

Can the ip itself leak? Not the delivery valves, sov or lines but the actual pump itself? I Ask because it leaks a thin black fluid around there looks like a mixture of oil and fuel smells like it too. But I still can't figure that out. Also the line from pre filter to fuel thermostat leaks down and is empty immediately after turning the car off. So it has to be leaking down somewhere. What about a faulty ip what are this symptoms?
