[QUOTE="Big Angry Hillbilly, post: 394320, member: 4453"] First off, why would you put a USED hp pump on an engine you need to take the cab off to work on. The gasket set is almost 200 dollars for crying out loud. Buy a new pump unless you like doing things twice. There is a superceded TSB for the pump replacement. Its a calibration update, which is unlikely to be included in your aftermarket calibration. It is, however worthy of note thar an updated/new pump has an updated part number from the pump that originally came in your truck. Luckily, my P0088 set when the 'replace the pump' TSB was still the fix for the issue. Hope this helps. [/QUOTE]
