I replaced the water pump, installed new gaskets and have no idea where this truck is leaking from. everytime i try and pressure test, it comes out from behind the water pump. ive reseated it about 12 times, and still the same result. has anyone had this issue and if so, what was the fix. it has the 5.0 non supercharged engine btw.

A picture would help. So would knowing where you live. Also mileage. Putting it as kindly as possible; you did something wrong! Although, it is possible you have a bad water pump. It has been known to happen.

Replaced a water pump on a 01 XJ8L a few years back (Airtex); thing wouldn't quit leaking. Pulled it off and replaced with an AC Delco, never to leak again. When I examined the Airtex, I noted it was leaking between mating surfaces that were supposed to be sealed at the factory.
