Is the fuel pump located in the cradle next to the tank, and if so is there anything in the tank that can be replaced ?

The ecu's, do they hold information eg fault codes and can they be wiped and rewritten ?

Had a few issues with the car and now someone else has got it but being given conflicting info, First bloke reckons he's replaced the Fuel pump in the tank and wiped and rewritten the ecu as it was holding fault codes, Bloke who's got it now says see that next to the tank, it's the fuel pump and doesn't look very new and that the ecu's don't hold fault codes and cannot be wiped.

Tillio, you know the first bloke and I'm leaning towards believeing the second.
