hi i if you guys dont remember i posted a thread last week about my fuel pump but i was able to drop the tank and replace the whole sending unit with a bosch one. but now the truck runs a lil weird from a stop it hesitates a lil or sometimes it will like cough. what can be wrong? thank you

 

Did you disconnect battery while changing? Have you tried it since? PCM may need to be reset. Other things I would check is to verify fuel pressure, Check and/or clean IAC and check TPS. (Disconnect battery while doing any of these except checking fuep pressure).

And if you have not done so, you can download service manual in FAQ/DIY section. That will be helpful also.
