Yes do this ! In my .02 thats not near enough for your 6.0. The stock intank pump is not even enough with minor upgrades. A stock 6.0 with a good tune will even clip the stock injectors at 80%+. The 6.0 engines are known for needing a little help in the fuel department and you have further crippled it with that pump!
